* libcsupport/src/newlibc_exit.c, score/src/threadhandler.c: Added
init/fini array support for ARM EABI. The __libc_init_array() and
__libc_fini_array() functions are provided by Newlib.
* rtems/score/cpu.h: Removed superfluous comments. Format. Include
by assembler support. Removed superfluous floating-point support.
Stack alignment is now 4.
* cpu_asm.S, rtems/score/cpu.h: There is no need to save the global
pointer (gp) in the thread register context since it is a system wide
constant and set-up with the C runtime environment.

* posix/src/psignal.c, posix/src/pthread.c, posix/src/pthreadjoin.c:
Correct signal processing during pthread_join. We are supposed to
unblock the thread waiting on a pthread_join(), dispatch the signal
handler, account for it potentially overwriting errno, and then have
the thread return to blocking within pthread_join().
PR 1867/cpukit
* posix/src/pthreadexit.c, posix/src/pthreadjoin.c: Correct
implementation of pthread_exit() and pthread_join() to support the
case where a thread is joinable but calls pthread_exit() before a
thread has attempted to join.

Split isrlevel into its own file to avoid a circular dependancy in
smp code.
* score/include/rtems/score/isrlevel.h: New file.

* netinet/ip_output.c: If a null or unreachable gateway is
specified either statically in networkconfig.h or from dhcp/bootp,
sendto() fails on multicast send with errno "118 Host is unreachable".
The failure occurs in networking file ip_output.c since it currently
requires all multicasts to have a valid route to the outside world.

PR 1775/filesystem
* libfs/src/nfsclient/src/nfs.c: NFSAddress NFS issue where read/write
problems when requested bytes greater than nfsStBlksize. Failure to
create files and symlinks.
* libblock/src/nvdisk-sram.c, libi2c/libi2c.c,
libmisc/shell/main_msdosfmt.c: Eliminate use of GNU old-style field
designator extension as recommended by clang.
* libcsupport/src/malloc_initialize.c: After discussion with Till
Straumann, revert the change from r1.12 to r1.13. This broke BSPs
with sbrk() support once the libbsp sbrk() framework was enhanced.
psim runs now.
