- Fix build on CURRENT with GCC 4.2

Submitted by:   tegge (maintainer)

Correct retrieval of stack address and size when getting the current
thread attributes for the main thread.

Add emulation of native threads (libc_r) method of getting the current
thread attributes (pthread_attr_get_np()) and adjust emulation of native
threads pthread_attr_getstackaddr() to return bottom of stack instead of
top of stack.

Correct emulation of native threads pthread_mutexattr_settype() when
selecting recursive mutexes.  Previously, the argument conversion before
calling the linuxthreads version of pthread_mutexattr_setattr() ended up
selecting errorcheck mutexes instead of recursive mutexes.

Check for NO_PIC and NO_PROFILE on FreeBSD >= 6.0.

Add sys/_pthreadtypes.h to allow compilation on FreeBSD >= 6.0.

Initialize signal trampoline variables earlier to avoid race in wrapper
around sigaction.

Fix known API wrapper bugs.

Port compile time options:

  Add option for using an alternate restart signal instead of SIGUSR2.

  Add options for adjustment of maximum thread stack size and maximum
  number of threads.

  Make all options start with LINUXTHREADS_

Note that complete FreeBSD source matching userland must be installed
in /usr/src when compiling this port.

Stop wrapping gethost* functions on 5.2-CURRENT.

Add option to ignore posix priority scheduling.
Add threadsafe versions of some libc functions on FreeBSD 4.x.
Register liblgcc_r_pic.a as installed for FreeBSD 5.x.

Restore gethostbyaddr_r wrapper and remove getpw{nam,uid}_r wrappers for
newer versions of FreeBSD 5.X.

Drop use of deprecated AINC variable.

Reenable use of ld(1) to restore the LINUXTHREADS_WRAP_API option.

Rename __thread to __xthread in prototypes to avoid conflict with
new gcc keyword.

Bump port revision.

Add new experimental option, LINUXTHREADS_WRAP_API, that adds wrapper
functions providing most of the native threads API while avoiding name
clashes by transparently prefixing all function names that directly
provide the linuxthreads API.

Make detection of unsafe calls to exit() optional and not default.

Fix build failure on 5.0-CURRENT by including necessary headers.

Let main thread do an exit(1) instead of an exit(0) on unclean program
termination (multiple active threads).

Register PIC archives when INSTALL_PIC_ARCHIVE has been defined.
Defining INSTALL_LIBLTHREAD_PIC_ARCHIVE causes installation and
registration of PIC archive for liblthread, which can be used to
generate a shared liblthread library for a different gcc installation.

Fix hang caused by a thread calling exit():

  - Block cancel signal while creating new thread to avoid losing
    the signal.

  - Terminate the process with _exit(1) if it's unsafe to continue
    calling atexit functions and destructors.

Handle internal race that caused pthread_cond_timedwait() to block   waiting for
a signal that wasn't sent.    

Backout library major number bump.  It wasn't needed.  Additionally,   ldconfig
-r didn't list the library, making it impossible for other   ports to depend on
the linuxthreads port.    

Update from version 2.1.3 to 2.2.3 of LinuxThreads.    

Use __error() from liblthread instead of the libc version.    

Reference _flockfile to ensure that the linuxthreads version is used.    

Initialize attributes for new threads with default values when a NULL  
pthread_attr_t is provided as argument to pthread_create.    

Use the correct pthread.h when compiling liblgcc_r.  Allow thread stacks  
larger than 16kB.  Make sure to call global destructors during shutdown.
