6bb9d3017c Fix compiler warning.
get_user_name returns const char *, but we were assigning the result
to a char * variable.

613c6d26bd Fix incorrect error message reported for non-existent users
Previously, lookups of non-existent user names could return "Success";
it will now return "User does not exist" by resetting errno.  This also
centralizes the user name lookup code in libpgport.

2c66f9924c Replace pg_asprintf() with psprintf().
This eliminates an awkward coding pattern that's also unnecessarily
inconsistent with backend coding.  psprintf() is now the thing to
use everywhere.

5b6d08cd29 Add use of asprintf()
Add asprintf(), pg_asprintf(), and psprintf() to simplify string
allocation and composition.  Replacement implementations taken from
NetBSD.

264aa14a2f pg_upgrade: Split off pg_fatal() from pg_log()
This allows decorating pg_fatal() with noreturn compiler hints, leading
to better diagnostics.

8396447cdb Create libpgcommon, and move pg_malloc et al to it
libpgcommon is a new static library to allow sharing code among the
various frontend programs and backend; this lets us eliminate duplicate
implementations of common routines.  We avoid libpgport, because that's
intended as a place for porting issues; per discussion, it seems better
to keep them separate.

The first use case, and the only implemented by this patch, is pg_malloc
and friends, which many frontend programs were already using.

At the same time, we can use this to provide palloc emulation functions
for the frontend; this way, some palloc-using files in the backend can
also be used by the frontend cleanly.  To do this, we change palloc() in
the backend to be a function instead of a macro on top of
MemoryContextAlloc().  This was previously believed to cause loss of
performance, but this implementation has been tweaked by Tom and Andres
so that on modern compilers it provides a slight improvement over the
previous one.

This lets us clean up some places that were already with
localized hacks.

Most of the pg_malloc/palloc changes in this patch were authored by
Andres Freund. Zoltán Böszörményi also independently provided a form of
that.  libpgcommon infrastructure was authored by Álvaro.

6dd9584507 Improve pg_upgrade's status display
Pg_upgrade displays file names during copy and database names during
dump/restore.  Andrew Dunstan identified three bugs:

*  long file names were being truncated to 60 _leading_ characters, which
   often do not change for long file names

*  file names were truncated to 60 characters in log files

*  carriage returns were being output to log files

This commit fixes these --- it prints 60 _trailing_ characters to the
status display, and full path names without carriage returns to log
files.  It also suppresses status output to the log file unless verbose
mode is used.

12ee6ec71f In pg_upgrade, dump each database separately and use
--single-transaction to restore each database schema.  This yields
performance improvements for databases with many tables.  Also, remove
split_old_dump() as it is no longer needed.

09ac603c36 Work around unportable behavior of malloc(0) and realloc(NULL, 0).
On some platforms these functions return NULL, rather than the more common
practice of returning a pointer to a zero-sized block of memory.  Hack our
various wrapper functions to hide the difference by substituting a size
request of 1.  This is probably not so important for the callers, who
should never touch the block anyway if they asked for size 0 --- but it's
important for the wrapper functions themselves, which mistakenly treated
the NULL result as an out-of-memory failure.  This broke at least pg_dump
for the case of no user-defined aggregates, as per report from
Matthew Carrington.

Back-patch to 9.2 to fix the pg_dump issue.  Given the lack of previous
complaints, it seems likely that there is no live bug in previous releases,
even though some of these functions were in place before that.

b98fd52a55 Silence -Wunused-result warning in contrib/pg_upgrade.
This is just neatnik-ism, but since we do it for comparable code in elog.c,
we may as well do it here.

3d6ec663bb Improve pg_upgrade's load_directory() function.
Error out on out-of-memory, rather than returning -1, which the sole
existing caller wasn't checking for anyway.  There doesn't seem to be
any use-case for making the caller check for failure here.

Detect failure return from readdir().

Use a less platform-dependent method of calculating the entrysize.
It's possible, but not yet confirmed, that this explains bug #6733,
in which Mike Wilson reports a pg_upgrade crash that did not occur
in 9.1.  (Note that load_directory is effectively new code in 9.2,
at least on platforms that have scandir().)

Fix up comments, avoid uselessly using two counters, reduce the number
of realloc calls to something sane.
