This makes gdbreplay share a bit more code with gdbserver, and paves
the way to share more in future. Including common-defs.h pulls in
defines and headers that gdb and gdbserver assume are always
defined/available too, such as for example _(), ansidecl.h or a set of
system headers. Including that revealed (static vs extern conflict)
gdbreplay had a local copy of perror_with_name (which exited directly
instead of throwing an error). So I removed gdbreplay's local copy,
and then added enough .o files until gdbreplay linked successfully.
Also, use xstrdup instead of strdup.
gdb/gdbserver/ChangeLog:
2018-06-08 Pedro Alves <palves@redhat.com>

common/errors.o, common/print-utils.o and utils.o.
* gdbreplay.c: Include "common-defs.h" instead of the two
'config.h's here. Don't include stdio.h, errno.h, stdlib.h,
string.h or alloca.h.
(perror_with_name): Delete.

We don't actually need to access the object through
"struct sockaddr *", so we don't need the union:

Building gdbserver in C++ mode shows:
gdb/gdbserver/tracepoint.c: In function ‘void* gdb_agent_helper_thread(void*)’:
gdb/gdbserver/tracepoint.c:7190:47: error: cannot convert ‘sockaddr_un*’ to ‘sockaddr*’ for argument ‘2’ to ‘int accept(int, sockaddr*, socklen_t*)’
fd = accept (listen_fd, &sockaddr, &tmp);
A few places in the tree already have an explicit cast to struct
sockaddr *, but that's a strict aliasing violation. Instead of
propagating invalid code, fix this by using a union instead.

Since gnulib alloca module was imported, we can include alloca.h in
both gdb and gdbserver unconditionally, so this patch adds inclusion
of alloca.h in common-defs.h. This patch also removes AC_FUNC_ALLOCA
in configure.ac because we don't need to check alloca any more.
This patch below is removed in fact.
[RFA/commit] include alloca.h if available.
https://www.sourceware.org/ml/gdb-patches/2010-08/msg00566.html
Since alloca.h is from gnulib now, we don't have to check malloc.h in
configure and include malloc.h in code. This patch also remove them
too.

This commit moves the inclusion of errno.h to common-defs.h and
removes all other inclusions. Note that prior to this commit
server.h included errno.h protected by "#ifdef HAVE_ERRNO_H".
This protection was added with the Windows CE port, which is
currently broken. Since no other platform needs this, I have
removed the protection and the configury to support it.

Now that we are using the gnulib string.h module, we don't need to
check for string.h or strings.h. This removes the last few checks
from the source and from the configure scripts.

With gnulib's unistd module, we can assume unistd.h is always present, and that
STDIN_FILENO, STDOUT_FILENO, STDERR_FILENO are always defined.
Don't remove unistd.h from GDB's configure.ac, as later tests in the
file use HAVE_UNISTD_H checks.

Right now there are two nightly commits to update a file in the tree
with the current date. One commit is for BFD, one is for gdb.
It seems unnecessary to me to do this twice. We can make do with a
single such commit.
This patch changes gdb in a minimal way to reuse the BFD date -- it
extracts it from bfd/version.h and changes version.in to use the
placeholder string "DATE" for those times when a date is wanted.
I propose removing the cron job that updates the version on trunk, and
then check in this patch.
For release branches, we can keep the cron job, but just tell it to
rewrite bfd/version.h. I believe this is a simple change in the
crontab -- the script will work just fine on this file.
This also moves version.in and version.h into common/, to reflect
their shared status; and updates gdbserver to use version.h besides.
* common/create-version.sh: New file.
* Makefile.in (version.c): Use bfd/version.h, common/version.in,
create-version.sh.
(HFILES_NO_SRCDIR): Use common/version.h.

Two modifications:
1. The addition of 2013 to the copyright year range for every file;
2. The use of a single year range, instead of potentially multiple
year ranges, as approved by the FSF.
gdb/ChangeLog:
* top.c (print_gdb_version): Update copyright year in version output.
gdb/gdbserverChangeLog:
* server.c (gdbserver_version): Update copyright year in version
output.
* gdbreplay.c (gdbreplay_version): Ditto.
This patch moves all includes of malloc.h, which were introduced
purely to get access to alloca's declaration, to server.h, next
to the include of alloca.h.
There is one exception: gdbreplay.c, which does not include server.h.
In this case, the include of alloca.h was simply moved up a bit, next
to the include of malloc.h.
gdb/gdbserver/ChangeLog:
* gdbreplay.c: Move include of alloca.h up, next to include of
malloc.h.
* server.h: Add include of malloc.h.
* mem-break.c: Remove include of malloc.h.
* server.c, tracepoint.c, utils.c, win32-low.c: Likewise.
On LynxOS, alloca is defined in allocal.h. This fixes one warning that
