* findvar.c (read_register_bytes read_register_gen
write_register_bytes read_register read_register_pid
write_register write_register_pid supply_register): Move multi-
thread handling down into these routines. Create XXX_pid routines
that allow register references to specify the pid.

read_sp write_sp read_fp write_fp): Move these routines from
infcmd to findvar to centralize the whole mess.

target_wait() to speed up remote debugging.

nicer looking new function calls (see changes to findvar.c).

support for O response.

all formatting issues, run-length encoding, and framing. getpkt
now handles error recovery, and frame detection.

control. (hardwire_readchar): Handle EINTR from read().

macros to use the hardware debugging functions in i386v-nat.c.
cyscm links against ../../gdb/{...}.o
Added a new target: libgdb-files. It creates a file of that name

is set, each file name has that prepended.
* xcoffread.c (read_xcoff_symtab): For C_FILE symbols, only use
the auxent if the symbol's name is ".file". From David Edelsohn
<c1dje@watson.ibm.com>.

calls vfprintf_unfiltered!

* annotate.c: ...to here, and make it use can_dereference.

version also, match on casted version strings, and match on
gdb startup case where the line numbers might be messed up.
* inflow.c (job_control, attach_flag, generic_mourn_inferior):
Remove, needed for both native and cross.
* target.c (attach_flag, generic_mourn_inferior): Put here.
* utils.c (job_control): Put here.
(terminal.h): Don't include anymore.
BROKEN_LARGE_ALLOCA. Do the cleanup before returning, rather than

config/i386/{xm-sun386.h,xm-i386m3.h,xm-i386mach.h},

BROKEN_LARGE_ALLOCA; with the above change it is no longer needed.
* main.c, fork-child.c, many config files: Remove all
SET_STACK_LIMIT_HUGE code; with the above changes it should no
longer be needed.
* symtab.c (lookup_partial_symbol): Use if and abort, not assert.
This avoids __eprintf troubles.
* main.c (main): Surround in #ifndef MAIN_OVERRIDE. Move
initialization code which needs to be called even if we bypass the
command line stuff into gdb_init.
* utils.c (fputs_unfiltered): Surround in #ifndef
FPUTS_UNFILTERED_OVERRIDE.
* Makefile.in (libgdb.a): New target.
* utils.c: Rearrange I/O stuff a bit so that all output goes
through fputs_unfiltered. Use vasprintf; removes arbitrary limit
which made %s not work with arbitrarily large strings.
* printcmd.c (printf_command): Use printf_filtered, not
printf_unfiltered and printf, now that arbitrary limit is gone.
