There is more to this patch than just more permissive
mode strings. Now if a socket can be opened with mode
"l2" for instance, and these options are effectively applied
to the socket-specific "r+b" default, not to "r".
* stream.c (parse_mode): New argument specifying a default
mode. The syntax is relaxed, allowing previously required
elements to be omitted.
(normalize_mode): New argument specifying a default mode.
Format mode is always called now, because an input string
is no longer necessarily a valid fopen string even in cases
when it doesn't specify any extensions.
(open_file, open_fileno, open_tail, open_command,
open_process): Use new normalize_mode argument for defaulting;
normalize_mode no longer defaults to "r".
* stream.h (stdio_mode_init_trivial): Macro removed.
(stdio_mode_init_blank, stdio_mode_init_r,
stdio_mode_init_rpb): New initializer macros.
(parse_mode, normalize_mode): Declarations updated.
* socket.c (sock_accept): In datagram socket case, use new
parse_mode argument for defaulting using stdio_mode_init_rpb,
rather than overriding a missing string with "r+b".
(open_sockfd): Likewise, and use new normalize_mode
argument similarly for defaulting the mode on a stream socket.
* txr.1: Documented mode string permissiveness.

* socket.c (struct dgram_stream): new rx_max member.
(make_dgram_sock_stream): New arguments: a struct stdio_mode,
and pointer to prototype dgram socket. If a size is specified
in the mode, then use that as rx_max. Otherwise if a prototype
socket is specified, use its rx_max as the new socket's rx_max.
Otherwise default on 65536.
(dgram_get_byte_callback): Use d->rx_max as the capture size,
rather than a hard-coded 65536.
(sock_accept): Use d->rx_max as capture size for datagram.
Parse the mode. Pass the parsed mode to make_dgram_sock_stream,
as well as the accepting socket, so it can set up the rx_max
for the new socket.
(open_sockfd): Parse the mode and pass to make_dgram_sock_stream.
* stream.c (parse_mode): Static function becomes extern.
* stream.h (parse_mode): Declared.
* txr.1: Documented.

FILE * stream if the mode specifies a buforder.

behavior of "i".

and linebuf. All members become bit fields of width 1.

(stdio_handle): New member, addr.
(stdio_stream_print): Obtain descr by calling get_prop
method rather than directly from h->descr, in case it is
dynamically computed. Use ~a rather than ~s for incorporating
string properties into printed form, to eliminate quotes.
(stdio_stream_mark): Mark new addr member.
(sock_get_prop, sock_set_prop): New static functions.
(stdio_set_sock_peer): Invalidate h->descr by setting
it to nil.
(make_stdio_stream_common): Initialize h->addr to nil.

variable is defined to 'y'.

for socket-related functionality.
(HAVE_SOCKETS, HAVE_GETADDRINFO): New configuration
preprocessor symbols.
Also, reordering the shell probing so that /usr/xpg4/bin/sh

* lib.c (subtypep): Handle subtype check here between
stream and stdio-stream as a special case, since streams
aren't structures related by inheritance, but built-ins.
(class_check): If the type of obj doesn't match the class
exactly, use a subtypep check. We need this because stream
functions use this check, and stdio streams are not of the
stream type now.

(make_stdio_stream_common): Use stdio_stream_s symbol for the
type of stdio streams.

(stdio_seek): Accept offset as val, which could be a fixnum
or bignum. Use new stdio_ftell and stdio_fseek functions

Function arguments are now allocated on the stack using alloca,
in conjunction with the struct alloc header structure.
The generic_funcall and apply functions are refactored
for this, as are most functions that take variadic arguments.

converts a list of arguments to args, and calls the new
generic_funcall.
(applyv): New static function: struct args wrapper
around apply_intrinsic.
(iapply): Converted to struct args.
(call): Static function removed. The call intrinsic
function binding now goes directly to generic_funcall.
(list_star_intrinsic, interp_fun): Converted to struct args.
(op_catch): Adjustments for bind_args, which requires
a struct args arglist.
(me_op): Must use the new minl and maxl, since minv and maxv
don't take lists any more.

GC. The issue being solved here is the accuracy of the gc_set function.
The existing impelmentation is too conservative. It has no generation
information about the memory location being stored, and so it assumes
the worst: that it is a location in the middle of a gen 1 object.
This is sub-optimal, creating unacceptable pressure against the
checkobj array and, worse, as a consequence causing unreachable gen 0
objects to be tenured into gen 1.
To solve this problem, we replace "val *" pointers with a structure
of type "loc" which keeps track of the object too, which lets us
discover the generation.
I tried another approach: using just a pointer with a bitfield
indicating the generation. This turned out to have a serious issue:
such a bitfield goes stale when the object is moved to a different
generation. The object holding the memory location is in gen 1, but the
annotated pointer still indicates gen 0. The gc_set function then
makes the wrong decision, and premature reclamation takes place.

generation. We do not need the in_malloc_range hack any more, since
we have the backpointer to the object.

Change to how locations are passed around, for the sake of generational
GC. The issue being solved here is the accuracy of the gc_set function.
The existing impelmentation is too conservative. It has no generation
information about the memory location being stored, and so it assumes
the worst: that it is a location in the middle of a gen 1 object.
This is sub-optimal, creating unacceptable pressure against the
checkobj array and, worse, as a consequence causing unreachable gen 0
objects to be tenured into gen 1.
To solve this problem, we replace "val *" pointers with a structure
of type "loc" which keeps track of the object too, which lets us
discover the generation.
I tried another approach: using just a pointer with a bitfield
indicating the generation. This turned out to have a serious issue:
such a bitfield goes stale when the object is moved to a different
generation. The object holding the memory location is in gen 1, but the
annotated pointer still indicates gen 0. The gc_set function then
makes the wrong decision, and premature reclamation takes place.

re-binding. C code now has to go through the dynamic environment lookup
to access things like *random-state*, or *stdout*. As part of this,
I'm moving some intrinsic variable and function initializations out of
eval.c and into their respective modules. Macros are are used to make
global variables look like ordinary C variables. This is very similar
to the errno trick in POSIX threads implementations.
* eval.c (looup_var, lookup_var_l): Restructured to eliminate silly
goto, the cobjp handling is gone.
(reg_fun, reg_var): Internal function becomes external.
reg_var registers a simple cons cell binding now, without any
C pointer tricks to real C global variables.
(c_var_mark): Static function removed.
(c_var_ops): Static struct removed.
(eval_init): Numerous initializations for streams, syslog, rand,
signals and others moved to their respective modules.
The new symbol variables user_package_s, keyword_package_s
and system_package_s are interned here, and the variables are
created in a special way.
* eval.h (reg_var, reg_fun): Declared.
* gc.c (prot1): Added assert that the loc pointer isn't null.
This happened, and blew up during garbage collection.
* lib.c (system_package, keyword_package, user_package): Variables
removed these become macros.
(system_package_var, keyword_package_var, user_package_var): New
global variables.
(system_package_s, keyword_package_s, user_package_s): New
symbol globals.
(get_user_package, get_system_package, get_keyword_package): New
functions.
(obj_init): Protect new variables. Initialization order of modules
tweaked: the modules sig_init, stream_init, and rand_init are moved
after eval_init because they register variables.
* lib.h (keyword_package, system_pckage, user_package): Variables
turned into macros.
(system_package_var, keyword_package_var, user_package_var): Declared.
(system_package_s, keyword_package_s, user_package_s): Declared.
(get_user_package, get_system_package, get_keyword_package): Declared.
* rand.c (struct random_state): Renamed to struct rand_state to
avoid clash with new random_state macro.
(random_state): Global variable removed.
(random_state_s): New symbol global.
(make_state, rand32, make_random_state, random_fixnum, random):
Follow rename of struct random_state.
