The argument order for posix_fallocate64 in the manual
was wrong, it was listed as [fd, len, offset] when it
should have been [fd, offset, len].
Verified io/fcntl.h has the right argument order, and it
does. Verified generated PDF.
In the posix_fallocate description in the manual we list various
drawbacks with the emulation, including the fact that a file opened
with O_APPEND fails with EBADF. Similarly a file opened with O_WRONLY
fails with EBADF. We must be able to emulate a compare-and-swap via
pread/compare/pwrite in order to make the emulation as safe as possible.
It is not acceptable to ignore the read failure because it could result
in significant data loss across all of the blocks. There is no other way
to make this work without a true atomic CAS and SIGBUS handler (which
is looking more attractive as a way to remove the race condition).
This patch adds O_WRONLY to the manual as another bullet to clarify the
limits of the emulation.
Manual looks good in PDF.
Handle signed integer overflow correctly. Detect and reject O_APPEND.
Document drawbacks of emulation.
This does not completely address bug 15661, but improves the situation
somewhat.
The four functions {alpha,version}sort{,64} take parameters of type
const struct dirent{,64} **, not const void *.

This is a minimal patch to remove _BSD_SOURCE and _SVID_SOURCE from
the documented user API, making them into aliases for _DEFAULT_SOURCE
with a #warning given, but keeping most of the features.h logic using
those macros and all the exising __USE_* conditionals, on the basis
that all the consequent cleanups will go in followup patches.
