file layout: moving share/txr/stdlib to stdlib.
This affects run-time also. Txr installations where the
executable is not in directory ending in ${bindir}
will look for stdlib rather than share/txr/stdlib,
relative to the determined installation directory.
* txr.c (sysroot_init): If we detect relative to the short
name, or fall back on the program directory, use stdlib
rather than share/txr/stdlib as the stdlib_path.
* INSTALL: Update some installation notes not to refer to
share/txr/stdlib but stdlib.
* Makefile (STDLIB_SRCS): Refer to stdlib, not
share/txr/stdlib.
(clean): In unconfigured mode, remove the old share/txr/stdlib
entirely. Remove .tlo files from stdlib.
(install): Install lib materials from stdlib.
* txr.1: Updated documentation under Deployment Directory Structure.
* share/txr/stdlib/{asm,awk,build,cadr}.tl:
Renamed to stdlib/{asm,awk,build,cadr}.tl.
* share/txr/stdlib/{compiler,conv,copy-file,debugger}.tl:
Renamed to stdlib/{compiler,conv,copy-file,debugger}.tl.
* share/txr/stdlib/{defset,doc-lookup,doc-syms,doloop}.tl:
Renamed to stdlib/{defset,doc-lookup,doc-syms,doloop}.tl.
* share/txr/stdlib/{each-prod,error,except,ffi}.tl:
Renamed to stdlib/{each-prod,error,except,ffi}.tl.
* share/txr/stdlib/{getopts,getput,hash,ifa}.tl:
Renamed to stdlib/{getopts,getput,hash,ifa}.tl.
* share/txr/stdlib/{keyparams,match,op,optimize}.tl:
Renamed to stdlib/{keyparams,match,op,optimize}.tl.
* share/txr/stdlib/{package,param,path-test,pic}.tl:
Renamed to stdlib/{package,param,path-test,pic}.tl.
* share/txr/stdlib/{place,pmac,quips,save-exe}.tl:
Renamed to stdlib/{place,pmac,quips,save-exe}.tl.
* share/txr/stdlib/{socket,stream-wrap,struct,tagbody}.tl:
Renamed to stdlib/{socket,stream-wrap,struct,tagbody}.tl.
* share/txr/stdlib/{termios,trace,txr-case,type}.tl:
Renamed to stdlib/{termios,trace,txr-case,type}.tl.
* share/txr/stdlib/{ver,vm-param,with-resources,with-stream}.tl:
Renamed to stdlib/{ver,vm-param,with-resources,with-stream}.tl.
* share/txr/stdlib/yield.tl: Renamed to stdlib/yield.tl.
* share/txr/stdlib/{txr-case,ver}.txr:
Renamed to stdlib/{txr-case,ver}.txr.
* gencadr.txr: Update to stdlib/place.tl.
* genman.txr: Update to stdlib/cadr.tl.
