* dcrt0.cc (set_os_type): Record OS name string.

(getprogname): Eliminate obsolete function.
(dll_crt0_1): Move initial strace initialization output to set_myself.
* exceptions.cc (interruptible): Add debugging output.
(interrupt_setup): New function.
(interrupt_now): Use interrupt_setup to set up common interrupt handler stuff.
(interrupt_on_return): Ditto.
(call_handler): Move signal_arrived arm and clear threads to region where
signalled thread is suspended or suffer races.
* pinfo.cc (set_myself): Output interesting information when strace is first
initialized.  Initialize progname here.
* sigproc.cc (sig_dispatch_pending): Modify to ensure that flush signal are
sent synchronously.
* strace.cc (strace_vsprintf): Move code into strace program.
* uname.cc (uname): Use 'osname' global to construct cygwin name + Windows type
+ version.
