  parsing embedded xml data structures.

From ucommon 1.4.1 to 1.4.2
- get address entry by family from list.

  building pure c mode link for c++ objects for deep embedding without
  libstdc++.
- changes to support QNX target builds.

From ucommon 1.4.0 to 1.4.1
- internalized getaddrinfo substituted on targets without addrinfo support.

- fixups for Solaris support

From ucommon 1.3.3 to 1.4.0
- socket::address constructors reorganized
- added mapped (shared memory) to ucommon library
- improved mingw32 support
- support for gcc < 3.0 (gcc 2.96, rhel-2.1 for example)
- socket initialization for msw.

From ucommon 1.3.2 to 1.3.3
- initialization of socket hinting for BSD stack.

- many testing asserts added to library for function argument preconditions.

From ucommon 1.2.5 to 1.3.0
- dynamic mutex resource locking, with new interface and supporting templates
  to automate operation.  This allows one to create exclusive access regions
  on demand without having to embed initialized mutexes in each instance of
  an object that requires serialization protection.

From ucommon 1.2.4 to 1.2.5
- restore sharing level at ConditionalLock commit if recursive locked.

- small change in use of sched.h for portability.
- unitialized mempager and reorg treemap purge.

From ucommon 1.2.1 to 1.2.2
- typo in exclusive conditional lock.

From ucommon 1.2.0 to 1.2.1
- conditional modify access can be asserted during active recursive share.

From ucommon 1.1.1 to 1.2.0
- adding conditional policies, ConditionalLock::concurrency() and
  ConditionalRW::sharing().
- Recursive support in conditional locking.
- SharedPointer derived from ConditionalRW and optimized.

From ucommon 1.1.1 to 1.1.2
- fix for OS/X.

From ucommon 1.1.0 to 1.1.1
- adjusted definition of priority scheduling and added realtime thread policies.

From ucommon 1.0.0 to 1.1.0

- fixed new operator when using stdcpp.
- conditionalrw locking scheme integrated for scheduling optimization.

From ucommon 0.9.2 to 1.0.0
- use std::runtime_exception instead of abort when using c++ runtime library
- crit macro allows std::runtime_exception processing for c++ runtime library
- check for old and new style c++ stream i/o classes, added OLD_STDCPP
- replaced NOSTDCPP with reversed & revised NEW_STDCPP flag unless OLD_STDCPP
- classes documented and doxygenized.
- expanded linked list support with head/tail and insert options.
- barrier with timed wait.

From ucommon 0.9.1 to 0.9.2
- fix critical bug in Socket::equal tests...

From ucommon 0.9.0 to 0.9.1
- removed AutoObject
- migrated thread functions to use pure win32 threading for mingw32; no
  more redhat pthread-win32.  This became possible when we dropped
  cancellable threads.
- fixed cc mode library build because libtool still forces libstdc++!

From ucommon 0.8.2 to 0.9.0
- slight change to thread init for pthread-win32 static libs.
- new steplock formed purely from staircase mutexes.
- new event timer for timed completion event signalling.

- conditional lock protect for shared recursive/short lock use.

From ucommon 0.8.0 to 0.8.1
- fix for pthread without setschedprio.

From ucommon 0.7.0 to 0.8.0

From ucommon 0.6.1 to 0.7.0
- added basic thread priority support
- changed base configure options to avoid collisions with other packages
- added getservice interface to get socket port #
- added charbuf template
- cidr policy chains simplified
- some rationalization and improvement in socket class with the ability
  to compare addresses, manipulate address lists, etc.
- string finding with deliminators.
- first pass at offering real documentation for the library via doxygen.

From ucommon 0.6.0 to 0.6.1
- support for static libpthreadGC2
- support for w32 address conversion

From ucommon 0.5.0 to 0.6.0
- detached & pooled thread exit support fixed
- equal test for socket address
