Instead of include a generic header (bits/signum-generic.h) and undef non-default values in an arch specific header (bits/signum.h) the new scheme uses a common definition (bits/signum-generic.h) and each architectures add its specific definitions on a new header (bits/signum-arch.h). For Linux it requires copy some system default definitions to alpha, hppa, and sparc. They are historical values and newer ports uses the generic Linux signum-arch.h. For Hurd the BSD signum is removed and moved to a new header (it is used currently only on Hurd). Checked on a build against all affected ABIs.

Its internal name is changed to __sys_siglist and __sys_sigabbrev to avoid static linking usage. The compat code is also refactored, since both Linux and Hurd usage the same strategy: export the same array with different object sizes. The libSegfault change avoids calling strsignal on the SIGFAULT signal handler (the current usage is already sketchy, adding a call that potentially issue locale internal function is even sketchier). Checked on x86_64-linux-gnu and i686-linux-gnu. I also run a check-abi on all affected platforms.

Its internal name is also changed to _sys_errlist_internal to avoid static linking usage. The compat code is also refactored by removing the over enginered errlist-compat.c generation from manual entried and extra comment token in linker script file. It disantangle the code generation from manual and simplify both Linux and Hurd compat code. The definitions from errlist.c are moved to errlist.h and a new test is added to avoid a new errno entry without an associated one in manual. Checked on x86_64-linux-gnu and i686-linux-gnu. I also run a check-abi on all affected platforms.

Maximum number of signals non multiple of word is rounded up. This patch also adds __NSIG_BYTES, which is the number of bytes required to represent the support number of signals. It is used on syscall which takes a sigset_t. Checked on x86_64-linux-gnu and i686-linux-gnu.

The default one uses a TLS structure, which will be place in the static TLS space (using __thread keyword). 2. Linux allocates on struct pthread and access it through THREAD_* macros. The default strategy has the disadvantage of increasing libc.so static TLS consumption and thus descreasing the possible surplus used in some scenarios (which might be mitigated by BZ#25051 fix). It is used only on Hurd, where accessing the thread point in single thread case is not straightforward (afaiu, Hurd developers could correct me here). The fallback static allocation used for allocation failure is also removed: defining its size is problematic without synchronize with translated messages (to avoid partial translation) and the resulting usage is not thread-safe. Checked on x86-64-linux-gnu, i686-linux-gnu, powerpc64le-linux-gnu, and s390x-linux-gnu.

"Libc-alpha" The strerrorname returns error number name (i.g. "EINVAL" for EINVAL) while strerrordesc returns string describing error number (i.g "Invalid argument" for EINVAL). Different than strerror, strerrordesc does not attempt to translate the return description and both functions return NULL for an invalid error number. They should be used instead of sys_errlist and sys_nerr and both are thread and async-signal safe. These functions are GNU extensions. Checked on x86-64-linux-gnu, i686-linux-gnu, powerpc64le-linux-gnu, and s390x-linux-gnu.
