- New functions: sigsetjmp, siglongjmp.
These were only available as macros up to now, but POSIX requires that
siglongjmp has to be available as function.

What changed:
-------------
Ignore non-absolute $HOME when started from native process * uinfo.cc (cygheap_user::ontherange): Ignore $HOME if it's not starting with a slash (aka, absolute POSIX Path). Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

- When started from a non-Cygwin process, check if $HOME starts with a
slash (absolute POSIX path). Otherwise ignore it.

Cygwin: Fix x86_64 memcpy/memset for n > 2GB https://cygwin.com/ml/cygwin/2015-07/msg00344.html: RtlFillMemory and RtlCopyMemory only work for size values up to 2GB. Fix this problem by using NetBSD code for memset and memcpy. Add entry points for memmove, wmemset, wmemmove, wmemcpy. Thanks to Roman Petrovski <RPetrovski@illumina.com> for pointing this out. * miscfuncs.cc (memset): x86_64 only: Implement in assembler. (memmove,memcpy): x86_64 only: Ditto.
