GetTokenUser() will have reported an adequate error message. These
error conditions almost can't happen, so users are unlikely to observe
this change.

This corrects messages for can't-happen errors. The corresponding "user
token" appears in the HANDLE argument of GetTokenInformation().

Backpatch certain files through 9.1

Darwin --enable-nls builds use a substitute setlocale() that may start a
thread. Buildfarm member orangutan experienced BackendList corruption
on account of different postmaster threads executing signal handlers
simultaneously. Furthermore, a multithreaded postmaster risks undefined
behavior from sigprocmask() and fork(). Emit LOG messages about the
problem and its workaround. Back-patch to 9.0 (all supported versions).

Coverity identified a number of places in which it couldn't prove that a
string being copied into a fixed-size buffer would fit. We believe that
most, perhaps all of these are in fact safe, or are copying data that is
coming from a trusted source so that any overrun is not really a security
issue. Nonetheless it seems prudent to forestall any risk by using
strlcpy() and similar functions.
Fixes by Peter Eisentraut and Jozef Mlich based on Coverity reports.
In addition, fix a potential null-pointer-dereference crash in
contrib/chkpass. The crypt(3) function is defined to return NULL on
failure, but chkpass.c didn't check for that before using the result.
The main practical case in which this could be an issue is if libc is
configured to refuse to execute unapproved hashing algorithms (e.g.,
"FIPS mode"). This ideally should've been a separate commit, but
since it touches code adjacent to one of the buffer overrun changes,
I included it in this commit to avoid last-minute merge issues.
This issue was reported by Honza Horak.
Security: CVE-2014-0065 for buffer overruns, CVE-2014-0066 for crypt()

Update all files in head, and files COPYRIGHT and legal.sgml in all back

Continuing 63f32f3416a8b4f8e057dc184e8e8eae734ccc8a, libpgcommon should
depend on libpgport, but not vice versa. But wait_result_to_str() in
wait_error.c depends on pstrdup() in libpgcommon. So move exec.c and
wait_error.c from libpgport to libpgcommon. Also switch the link order
in the place that's actually used by the failing ecpg builds.
The function declarations have been left in port.h for now. That should
perhaps be separated sometime.
