10b1416d2f Update the documentation for setpgrp(2) to reflect the access control 
checks that the code actually performs.  Judging from the 4.2BSD
release notes, the docs have only been out of date for 20 years.

Daniel Eischen
5c70dac879 Modify the implementation of libc semaphores so that they can be 
overridden by the threads library to provide a userland version
of non-pshared semaphores and cancellation points.  Also add
a sem_timedwait().

The libc version of semaphores always uses kernel semaphores
regardless of whether pshared is set or not.  When threads are
not present, it is difficult to get sem_wait() or sem_timedwait()
to do the right thing (since pthread_cond_timedwait() and
pthread_cond_wait() are stubs in libc and just return immediately).

307649e2f3 Use 'uint32_t' instead of 'long' when a 32-bit integer is intended. 
This results in no functional change, aside from fixing a data
corruption bug on LP64 platforms.  The code here could still use a
significant amount of cleanup.

e18c6616e2 Bring the *printf(3) documentation up to date with the code: 
- Update and improve the documentation for %[aA]
  o Like %[eE], %[aA] may round the result if a precision is specified.
  o Grammar police: Fix a split infinitive.
  o The FreeBSD implementation does better than the minimum required
    by C99 (literal translation of the mantissa).  The digit before
    the hexadecimal-point is never 0 unless the number itself is 0.
  o Clarify that the exponent field represents a decimal exponent of 2.
  o Discuss the fact that multiple valid representations are possible.
  o Remove the entry in the BUGS section claiming that %[aA] is not
    implemented.

- Remove the entry in the BUGS section claiming that the ' flag for
  printing thousands separators is unimplemented for floating-point.

- Remove the entry in the BUGS section claiming that the L modifier
  reduces the precision to "double" before conversion.

904322a502 Fix some bugs affecting the %a and %A format specifiers. Since 
these are not fully implemented and ifdef'd out, the bugs have
never manifested themselves.  Specifically:

	- Fix a memory leak in the case where %a follows another
	  floating-point format.
	- Make the %a/%A code behave like %e/%E with respect to
	  precision.
	- It is no longer valid to assume that '-' and '0x' are
	  mutually exclusive.
	- Address other minor issues.

cc3782cbc7 Enable cancellation point in sem_wait, it is required by POSIX. 
For pshared semaphore, this commit still does not enable cancellation
point, I think there should be a pthread_enter_cancellation_point_np
for libc to implement a safe cancellation point.
