VG_(record_startup_wd) which records the working directory at startup,
and VG_(get_startup_wd) which later tells you what value was recorded.
This works because all uses of VG_(getcwd) serve only to record the
directory at process start anyway. The motivation is that AIX does
not support sys_getcwd directly, so it's easier for the launcher to
ship in the required value using an environment variable. On Linux
sys_getcwd is used as before.

- AIX implementations of various stuff, nothing surprising.
- For all platforms: make VG_(read) and VG_(write) return (negative)
actual error values rather than producing -1 for all failures.

changes from r4341 through r4787 inclusive). That branch is now dead.
Please do not commit anything else to it.
For the most part the merge was not troublesome. The main areas of
uncertainty are:
- build system: I had to import by hand Makefile.core-AM_CPPFLAGS.am
and include it in a couple of places. Building etc seems to still
work, but I haven't tried building the documentation.
- syscall wrappers: Following analysis by Greg & Nick, a whole lot of
stuff was moved from -generic to -linux after the branch was created.
I think that is satisfactorily glued back together now.
- Regtests: although this appears to work, no .out files appear, which
is strange, and makes it hard to diagnose regtest failures. In
particular memcheck/tests/x86/scalar.stderr.exp remains in a
conflicted state.
- amd64 is broken (slightly), and ppc32 will be unbuildable. I'll
attend to the former shortly.

being executed then propagate the error from the stat instead of just
return ENOACCES all the time. Fixes bug #110208.

- m_main: if --log-file-qualifier applies, do not add ".pid"
at the end of the name
- Fix the logic which detected whether the just-devised name
already existed. This was broken (by me) because it could not
distinguish the reasons for failing to open the logfile.
Doing this required changing the return type of VG_(open)
from Int to SysRes (to make failure reasons visible) and
that's the cause of most of the changes.
