* libcsupport/Makefile.am, libcsupport/include/rtems/malloc.h,
libcsupport/src/malloc_walk.c, libcsupport/src/posix_memalign.c,
libcsupport/src/realloc.c, score/src/heapwalk.c: Add rtems_memalign
as helper and as exposed nmemalign variant with few restrictions.
Also turn on compilation of _Heap_Walk but make forced calls to it
conditionally compiled. This should allow more flexibility to the
user as to run-time checking of the heap.
* libcsupport/src/rtems_memalign.c: New file.
* sapi/include/confdefs.h, score/src/mpci.c, score/src/objectmp.c,
score/src/objectnametoid.c, score/src/objectnametoidstring.c:
Multiprocessing compiles again and survives initialization. The
recent object name and confdefs.h changes had broken it.
* sapi/include/rtems/fatal.h, score/include/rtems/score/coremutex.h,
score/include/rtems/score/interr.h,
score/inline/rtems/score/thread.inl, score/src/coremutexseize.c:
Modifications to aid in full path testing.
* score/include/rtems/score/object.h,
score/src/objectextendinformation.c,
score/src/objectinitializeinformation.c,
score/src/objectshrinkinformation.c: Eliminate name_table since it is
not used.

score/src/objectextendinformation.c,
score/src/objectgetnameasstring.c, score/src/objectmp.c,
score/src/objectnametoid.c: Convert the Objects_Name type from a
simple type to a union of an unsigned 32 bit integer and a pointer.
This should help eliminate weird casts between u32 and pointers in
various places. The APIs now have to explicitly call _u32 or _string
versions of helper routines. This should also simplify things and
eliminate the need for ugly casts in some cases.
* score/src/objectclearname.c, score/src/objectcomparenameraw.c,
score/src/objectcomparenamestring.c, score/src/objectcopynameraw.c,
score/src/objectcopynamestring.c: Removed.
* rtems/src/eventsurrender.c, rtems/src/ratemonperiod.c,
score/src/threadqdequeue.c, score/src/threadqdequeuefifo.c,
score/src/threadqdequeuepriority.c: Fix bugs encountered while
testing and clean up more code.

score/src/threadqfirstfifo.c, score/src/threadqfirstpriority.c,
score/src/threadqflush.c, score/src/threadqrequeue.c,
score/src/threadqtimeout.c: Refactor thread queue enqueue and event
blocking synchronization critical sections. This resulted in three
copies of essentially the same hard to test critical section code
becoming the one shared routine _Thread_blocking_operation_Cancel. In
addition, the thread queue and event code now share a common
synchronization enumerated type. Along the way, switches were
reworked to eliminate dead code generated by gcc and comments and
copyrights were updated.
* score/include/rtems/score/threadsync.h,
score/src/threadblockingoperationcancel.c: New files.
* score/include/rtems/score/wkspace.h,
score/inline/rtems/score/wkspace.inl, score/src/wkspace.c: Do not
inline _Workspace_Free or _Workspace_Allocate since they are not
always inlined and actually smaller overall as subroutines. They are
not particularly time critical so inlining is not absolutely
necessary.
* posix/Makefile.am, posix/include/rtems/posix/cond.h,
posix/include/rtems/posix/mutex.h, posix/inline/rtems/posix/cond.inl,
posix/inline/rtems/posix/mutex.inl: Do not include POSIX Mutex or
Condition Variable object get helpers because they are more
complicated than the norm. They can implicitly perform a create. They
cross the line as being too complex and large to inline since they
negatively impact size and binary test coverage.
* posix/src/condget.c, posix/src/mutexget.c: New files.
* libcsupport/Makefile.am, libcsupport/include/rtems/malloc.h,
libcsupport/src/free.c, libcsupport/src/malloc.c,
libcsupport/src/malloc_deferred.c,
libcsupport/src/malloc_initialize.c, libcsupport/src/malloc_p.h,
libcsupport/src/malloc_sbrk_helpers.c,
libcsupport/src/posix_memalign.c: Place all deferred free code and
place it in subroutines. Add plugin for dirtying allocated memory to
assist in debugging. Clean up comments and spacing as needed.
* libcsupport/src/malloc_dirtier.c: New file.
* libcsupport/Makefile.am: Add malloc_sbrk_helpers.c.
* libcsupport/include/rtems/malloc.h,
libcsupport/src/malloc.c, libcsupport/src/malloc_initialize.c,
libcsupport/src/malloc_p.h,
libcsupport/src/malloc_statistics_helpers.c: Make sbrk()
support pluggable and optional. This eliminates the need for
heap extend and sbrk in the minimum footprint which is ~2.5K on
the SPARC.
* sapi/include/confdefs.h: Add the following configuration points:
+ CONFIGURE_MALLOC_STATISTICS
+ CONFIGURE_MALLOC_BSP_SUPPORTS_SBRK
* libcsupport/src/malloc_sbrk_helpers.c: New file.
* score/inline/rtems/score/isr.inl: Fix spacing.
* score/src/apimutexallocate.c: Fix spacing.
* score/src/coremsgseize.c: Check for message pending instead of
message pending count to avoid dead code from inlined chain routine.
It checks if the chain is empty so is redundant to count == 0.
* configure.ac: Fix typo in the strict order mutex CPU OPTs test.
* libmisc/shell/shell.c: Handle '#' comment characters correctly.
* libblock/include/rtems/flashdisk.h: Add docmentation about the
control fields. Add more control fields to handle the flash when
full.
* libblock/src/flashdisk.c: Fix the descriptor erase test so it
detects a descriptor is erased. Add support for unavailable blocks
the user can configure. Print the used list as a diag. Fix the bug
when a page is detected as failed and present on more than one
queue. Add a count to the queues so queue length can be used to
manage compaction.
* score/src/threadhandler.c, sapi/src/exshutdown.c:
cannot call _fini via atexit() from rtems_shutdown_executive()
because at the point where rtems_shutdown_executive is called
the C-library is already dead.
Instead, register an atexit(_fini) after calling _init().
* configure.ac: fixed bug that always enabled strict order
mutexes.
* score/inline/rtems/score/coremutex.inl: Fixed coding standard.
* score/src/coremutex.c: Add the holder's thread to the lock_mutex
list if the mutex is initialised locked.
* libnetworking/rtems/rtems_glue.c: Changed semaphore error
message to show the error is an rtems-net error.
* libmisc/monitor/mon-network.c: Removed warnings.
* telnetd/icmds.c: Changed shell_* to rtems_shell_*.
* score/Makefile.am: Fixed typo that stopped 'make tags' working.

libmisc/shell/warnx.c: New. Ported from BSD.
* libmisc/shell/shellconfig.h: Add the cp command.
* libmisc/Makefile.am: Add the new files to the shell.
* libmisc/shell/shell.c, libmisc/shell/shell.h: Add scripting
support.
* libblock/src/flashdisk.c: Fixed disk drive count size setting
bug.
* configure.ac, score/include/rtems/score/coremutex.h,
score/inline/rtems/score/coremutex.inl: Add the ability to disable
inlining coremutex seize. This reduces the code size and also
improves the process of coverage analysis.
* score/src/coremutexseizeintr.c: New file.
* configure.ac, score/include/rtems/score/coremutex.h,
score/include/rtems/score/thread.h,
score/inline/rtems/score/coremutex.inl,
score/src/coremutexsurrender.c, score/src/threadinitialize.c: Add
support for proper stacking of priority inheritance on mutexes as
well as enforce proper order of release.
