- Stop adding trailing '\n'. The servent_unpack() doesn't expect
lines terminated with '\n'.
- Treat '+' as special only when in compat mode, and simplify
the logic bit.
- Reduce duplicate code.
- While SPARC V9 allows tininess to be detected either before or after
rounding (impl. dep. #55), the SPARC JPS1 responsible for SPARC64 and
UltraSPARC processors defines that in all cases tinyness is detected
before rounding, therefore rounding up to the smallest normalised
number should set the underflow flag.
- If an infinite result is rounded down, the result should have an
exponent 1 less than the value for infinity.

Use thr_once() with once_t controls to initialize various thread_key_t
objects used to provide per-thread storage in the RPC code. Almost all
of these used double-checking with a dedicated mutex (tsd_lock) to do this
before. However, that is not always safe with more relaxed memory orders.
There were also other bugs, such as one in __rpc_createrr() that caused a
new key to be allocated each time __rpc_createrr() was invoked.
- The OPSZ macro actually only does the right thing for int32 and int64
operands but not for double and extended double ones. Instead of trying
to fix the macro just nuke it and unroll the loops in the correct way
though as extended double operands turn out to be the only special case.
- For FxTO{s,d,q} the source operand is int64 so rs2 has to be re-decoded
after setting type accordingly as it's generally decoded using the low
2 bits as the type, which are 0 for these three instructions.
- Similarly, in case of F{s,d,q}TOx the target is int64 so rd has to be
re-decoded using not only the operand mask appropriate for int64 but
also the correct register number encoding.
- Use const where appropriate.
- Wrap long lines.

In _gettemp(), check that the length of the path doesn't exceed
MAXPATHLEN. Otherwise the path name (or part of it) may not fit to
carrybuf causing a buffer overflow.

(S)LIST_HEAD_INITIALIZER takes a (S)LIST_HEAD as an argument.
Fix some wrong usages.

Better glibc compatibility for getline/getdelim:
- Tolerate applications that pass a NULL pointer for the buffer and
claim that the capacity of the buffer is nonzero.
- If an application passes in a non-NULL buffer pointer and claims the
buffer has zero capacity, we should free (well, realloc) it
anyway. It could have been obtained from malloc(0), so failing to
free it would be a small memory leak.

Add an internal _once() method. This works identical to pthread_once(3)
with the additional property that it is safe for routines in libc to use
in both single-threaded and multi-threaded processes. Multi-threaded
processes use the pthread_once() implementation from the threading library
while single-threaded processes use a simplified "stub" version internal
to libc.
Add a new errno, ENOTCAPABLE, to be returned when a process requests an
operation on a file descriptor that is not authorized by the descriptor's
capability flags.

Add two new fcntls to enable/disable read-ahead:
- F_READAHEAD: specify the amount for sequential access. The amount is
specified in bytes and is rounded up to nearest block size.
- F_RDAHEAD: Darwin compatible version that use 128KB as the sequential
access size.
A third argument of zero disables the read-ahead behavior.
Please note that the read-ahead amount is also constrainted by sysctl
variable, vfs.read_max, which may need to be raised in order to better
utilize this feature.
Thanks Igor Sysoev for proposing the feature and submitting the original
version, and kib@ for his valuable comments.
The fd_mask type is an unsigned long, not an int, so treat the mask as a
long instead of an int when examining the results of select() to look for
RPC requests. Previously this routine would ignore RPC requests to sockets
whose file descriptor mod 64 was greater than 31 on a 64-bit platform.
