b0bf75c83c file == NULL: 
Issue __sflush() before possible setting O_APPEND mode or ftruncate(),
write to wrong place may occurse oserwise.
Use simplified _sseek() to the start, if no O_APPEND is set, instead
of _fseeko() (_sseek() to the end, if O_APPEND, occurse later, as for
file != NULL).
Don't check seek error return, as original fopen() and freopen() never
does.

5b1deb3ce8 Return length from fwopen() file callback instead of zero. 
The symptom is that syslog() fails to log anything but the "ident"
string if LOG_PERROR is specified to openlog(3) and the extensible
printf is in action.

For unclear, likely quaint historical reasons, syslog uses fwopen()
on a stack buffer, rather than using the more straightforward
and faster snprintf().

Along the way, fflush(3) is called, and since the callback writer
function returns zero instead of the length "written", __SERR
naturally gets set on the filedescriptor.

The extensible printf, in difference from the normal printf refuses
to output anything to an __SERR marked filedescriptor, and thus
the actual syslog message is supressed.

da4ab3aa26 In DCE 1.1, the time_low value is defined as an unsigned 32-bit 
integer.  Presently, our implementation employs an approach that
converts the value to int64_t, then back to int, unfortunately,
this approach can be problematic when the the difference between
the two time_low is larger than 0x7fffffff, as the value is then
truncated to int.

To quote the test case from the original PR, the following is
true with the current implementation:

865e1a56-b9d9-11d9-ba27-0003476f2e88 < 062ac45c-b9d9-11d9-ba27-0003476f2e88

However, according to the DCE specification, the expected result
should be:

865e1a56-b9d9-11d9-ba27-0003476f2e88 > 062ac45c-b9d9-11d9-ba27-0003476f2e88

This commit adds a new intermediate variable which uses int64_t
to store the result of subtraction between the two time_low values,
which would not introduce different semantic of the MSB found in
time_low value.

0ec15b18a2 o compat_group() and files_group() are more complicated than I thought 
in rev. 1.34.  Mainly I missed the fact that the buffer is used for two
purposes:

1) storing a group line from the group file;

2) __gr_parse_entry() parses the buffer and tries to put the group
members to the remaining part of the buffer and can fail if there
is no enough room for them.

Re-arrange the buffer size checks to account the latter case.

5355c74026 Use some math tricks in arena_run_reg_dalloc() to avoid actual division, as 
well as avoiding a switch statement.  This change has no significant impact
to performance when branch prediction is successful at predicting the sizes
of objects passed to free(), but in the case that the object sizes are
semi-random, this change has the potential to prevent many branch prediction
misses, thus improving performance substantially.

Take advantage of alignment guarantees in ipalloc(), and pad object sizes to
something less than a power of two when possible.  This has the potential
to substantially reduce internal fragmentation for objects allocated via
posix_memalign().

Avoid an unnecessary pow2_ceil() call in arena_ralloc().

ea84e2b899 - Move _Qp_* and __dtoul from FBSDprivate to the list of FBSD_1.0 symbols 
as well as add __sparc_utrap_install to FBSD_1.0; these are required by
  the SCD libc 64 psABI and thus meant to be officially exported symbols.
- Remove the __fpu_* entries as well as the __sigtramp entry altogether as
  these are internal to the libc FPU emulation and the signal trampoline
  initialization in sigaction(2) respectively and thus don't need to be
  externally visible.
- Add __sparc_utrap_setup to the list of FBSDprivate symbols as it's used
  in src/lib/csu/sparc64/crt1.c to initialize the libc FPU emulation (I
  think alternatively src/lib/csu/sparc64/crt1.c could be changed to use
  __sparc_utrap_install instead, at the expense of increasing the size of
  executables a bit).
- Add an entry for the vfork symbol to the FBSD_1 list and entries for it's
  associated symbols generated by the RSYSCALL() macro to the FBSDprivate
  list. There's some magic in place that automatically generates code for
  vfork() if there's no explicit MD code for it so it might make sense to
  move these symbols from the MD symbol map files to a MI one.

The last two changes make the libc symbol versioning useable on sparc64.

f76963aba1 Don't test if RES_INIT is set to see res_state structure is 
initialized.  Some application may reset RES_INIT.  Use the
way in __res_vinit(), instead.

makes run split/coalesce operations of complexity lg(n) rather than n.

cf01f0d7c5 Add init_lock, and use it to protect against allocator initialization 
races.  This isn't currently necessary for libpthread or libthr, but
without it external threads libraries like the linuxthreads port are
not safe to use.

1c6d5bde6c Refactor per-run bitmap manipulation functions so that bitmap offsets only 
have to be calculated once per allocator operation.

Make nil const.

Update various comments.

Remove/avoid division where possible.

For the one division operation that remains in the critical path, add a
switch statement that has a case for each small size class, and do division
with a constant divisor in each case.  This allows the compiler to generate
optimized code that does not use hardware division [1].

9fe1984e64 Add __gdtoa to the list of FreeBSD private symbols. Unfortunately, 
this is used by some 3rd party applications when {e,f,g}cvt() are
not found.  POSIX defines the xcvt() funtions but says they are
deprecated in favor or sprintf().  We'll import these functions
from OpenBSD and remove __gdtoa() from the exported interfaces
when libc version is bumped.

cd70100e5d Optimize runtime performance, primary using the following techniques: 
* Avoid choosing an arena until it's certain that an arena is needed
    for allocation.

  * Convert division/multiplication to bitshifting where possible.

  * Avoid accessing TLS variables in single-threaded code.

  * Reduce the amount of pointer dereferencing.

  * Move lock acquisition in critical paths to only protect the the code
    that requires synchronization, and completely remove locking where
    possible.
