common-defs.h: include <stdarg.h> before <stdio.h>
When trying to build gdbserver on ppc-lynx178, the compiler reports
while trying to compile gdbserver/ax.c that vsprintf is not declared.
Looking at my C99 reference manual (a draft), I see the following
synopsis:
#include <stdarg.h>
#include <stdio.h>
int vsprintf(char * restrict s, [etc]);
Looking at stdio.h on LynxOS-178, if found where vsprintf gets
declared:
#if defined(__varargs_h) || defined(__stdarg_h) \
|| defined(_VARARGS_H) || defined(_STDARG_H)
extern int vsprintf _AP((char *, const char *, va_list));
#endif
Digging further, I noticed that common-defs.h, which is included
via server.h, includes stdarg.h after including stdio, explaining
why vsprintf does not get declared in this case.
This patch fixes the problem by including stdarg.h before stdio.h.
gdb/ChangeLog:
* common/common-defs.h: Move <stdarg.h> #include ahead of
<stdio.h> #include.
Tested on x86_64-linux.

# define EXTERN_C extern "C"

Make functions and variables exported by the IPA be extern "C"
Functions and variables that are exported by the IPA DSO (that
GDBserver needs to look up) should have "C" mangling, thus be declared
with extern "C".
Function and variable declarations need the extern "C" marker, but
variable definitions can't be marked extern, so the patch splits
IP_AGENT_EXPORT into three.
Building in C++ mode revealed that a few variables were missing
IP_AGENT_EXPORT, thus the IPA has been broken when stripped, even in C
mode... So this ends being a bug fix as well.
