aa64e11b02 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	- It is no longer valid to assume that '-' and '0x' are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.

7948e91c15 Mostly mechanical rework of libalias:
Makes it possible to have multiple packet aliasing instances in a
single process by moving all static and global variables into an
instance structure called "struct libalias".

Redefine a new API based on s/PacketAlias/LibAlias/g

Add new "instance" argument to all functions in the new API.

Implement old API in terms of the new API.

f9aac56ad7 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.

f04f7ffd82 o We are not required to initialize an invalid rwlock. So axe all that
code and simply return EINVAL (which is allowed by the standard) in
  all those pthread functions that previously initialized it.

o Refactor the pthread_rwlock_[try]rdlock() and pthread_rwlock_[try]wrlock()
  functions. They are now completeley condensed into rwlock_rdlock_common()
  and rwlock_wrlock_common(), respectively.

o If the application tries to destroy an rwlock that is currently
  held by a thread return EBUSY where it previously went ahead and
  freed all resources associated with the lock.

o Refactor _pthread_rwlock_init() to make it look (relatively) sane.

o When obtaining a read lock on an rwlock the check for whether it
  would exceed the maximum allowed read locks should happen *before*
  we obtain the lock.

o The pthread_rwlock_* functions shall *never* return EINTR, so make
  sure to requeue/resuspend the thread if it encounters such an error.

o Make a note that pthread_rwlock_unlock() needs to ensure it holds a
  lock on an rwlock it tries to unlock. It will be implemented in a
  separate commit because it requires some additional rwlock infrastructure.

ca8db354f6 - Move the code to try to open a single chunk file and prompt for the
associated floppy if needed into a static split_openfile() function.
- Use this function in splitfs_open() to open the first chunk rather
  than using open() directly.  This allows the first chunk to be located
  on a different disk than the actual foo.split file.

6722bb8a10 Fix a bug that could result in a null pointer dereference in
getpwent(3) or getpwuid(3) when using NIS adjunct maps.  The bug was
present in the internal `nis_passwd' function.  The lookup in the
adjunct map used the name passed into `nis_passwd', however no name
was of course supplied by getpwent or getpwuid.  Correctly use the
name from the `struct pwd' that was found instead.

c74cd0c713 Clarify the behavior of ptrace(2) a little bit: the tracing process
must first attach to the traced process.  If the tracing process
exits without detaching, the traced process will be killed rather
than continued.  For the duration of the tracing session, the traced
process is reparented to the tracing process (with resulting expected
behaviors).  It is permissible to trace more than one other process
at a time.  When using waitpid() to monitor the behavior of the traced
process, signals are intercepted: they may optionally then be
forwarded using ptrace().  Signals are generated normally by and for
the process, but also by the tracing facility (SIGTRAP).

9b32167d5f It was reported that when using nss_ldap, getgrent(3) would behave
incorrectly when encountering `large' groups (many members and/or many
long member names).  The reporter tracked this down to the glibc NSS
module compatibility code (nss_compat.c): it would prematurely record
that a NSS module was finished iterating through its database in some
cases.

Two aspects are corrected:

1. nss_compat.c recorded that a NSS module was finished iterating
   whenever the module reported something other than SUCCESS.  The
   correct logic is to continue iteration when the module reports
   either SUCCESS or RETURN.  The __nss_compat_getgrent_r and
   __nss_compat_getpwent_r routines are updated to reflect this.

2. An internal helper macro __nss_compat_result is used to map glibc
   NSS status codes to BSD NSS status codes (e.g. NSS_STATUS_SUCCESS ->
   NS_SUCCESS).  It provided the obvious mapping.

   When a NSS routine is called with a too-small buffer, the
   convention in the BSD NSS code is to report RETURN.  (This is used
   to implement reentrant APIs such as getpwnam_r(3).)  However, the
   convention in glibc for this case is to set errno = ERANGE and
   overload TRYAGAIN.  __nss_compat_result is updated to handle this
   case.

b5d5c1e2e6 Add a simple work-around for deadlocking on recursive read locks
on a rwlock while there are writers waiting.  We normally favor
writers but when a reader already has at least one other read lock,
we favor the reader.  We don't track all the rwlocks owned by a
thread, nor all the threads that own a rwlock -- we just keep
a count of all the read locks owned by a thread.
