0738a9d791 Nuke ascii2addr() and addr2ascii(). They have no consumers anywhere 
in FreeBSD, and originated from INRIA IPv6.

Stub out netstat reference to addr2ascii() I mistakenly introduced.
Update misleading man page sections.

Merge NetBSD's getnameinfo() AF_LINK extensions for a portable way to
print link-layer addresses given a sockaddr_dl(), minus the IEEE 1394
bits which don't map directly to our code.

Obtained from:	NetBSD (getnameinfo.c)

3de91924d2 Move _posix1e_acl_name_to_id out of acl_support.c and into 
acl_from_text.c.  Since acl_from_text.c is the only place it
is used, we can now make this internal utility function "static."

As a bonus, acl_set_fd() no longer pulls in getpwuid() for no reason.

a1e21ebd26 Modify chunk_alloc() to prefer mmap()ed memory over sbrk()ed memory. 
This has no impact unless USE_BRK is defined (32-bit platforms), in
which case user allocations are allocated via mmap() if at all possible,
in order to avoid the possibility of unreclaimable chunks in the data
segment.

Fix an obscure bug in base_alloc() that could have allowed undefined
behavior if an application were to use sbrk() in conjunction with a
USE_BRK-enabled malloc.

4e9ace58c2 On FreeBSD/arm, any value > 50 bits will result in a rediculously huge 
number being returned for mktime and timegm calls.  Choose 48 because
that works well.  This does reduce the dynamic range of tm_year from
about 2 billion years down to "only" about 9 million years.  Please
contact me if this restriction poses a problem.

Due to the complexity of the code, I admit that I didn't trace down
what, exactly, was overflowing with longer bits.  This fixes software
that we run on the embedded systems we have.

39a9779535 Prefer "to be modified" over "to be opened for writing". 
This is quite tricky situation, because we allow to open a file with
O_RDONLY|O_TRUNC. O_TRUNC modifies a file, but we actually don't open
it for writing. EISDIR is also returned when we try to open a directory
O_RDONLY|O_TRUNC, which is correct.
POSIX says that "The result of using O_TRUNC with O_RDONLY is undefined.",
we choose to accept it (Solaris did the same), that's why "to be modified"
seems more accurate to me.

3c7ee268c4 Workaround for (what seems to be) compiler error for gcc 3.4.6. On 
i386 with default optimization level (-O2), va_list pointer ap in the
__v2printf function is advanced before the use. That cause argument
shift and garbage instead last argument in printf-family when xprintf is
activated.

The nsswitch is easy victim of the bug.

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

Don't check seek error return, as original fopen() and freopen() never

1c0399f798 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.

513c2a1064 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.

e03f872cad 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.

64896f5bfe 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().
