Returns the process's environment concatenated into a single block of
null-terminated strings, along with the length of the environment block.
Adds an associated PICOM_ENVIRON commune_process handler.
win32env_to_cygwenv handles converting wchar to char and some other
minor taks. Optionally it handles converting any paths in variables to
posix paths.
This will be useful for implementing /proc/<pid>/environ
commit 67fd2101 introduced a bad bug. Changing sys_privs to a static
area and just returning a pointer is nice... *if* the calling code doesn't
call free() on it. Make sure callers check pointer for sys_privs and
refrain from calling free, if so.

GNU no longer encourages the use of documentation mirrors, to avoid
referring to obsolete documentation. Also www.fsf.org/manual/ is
just a redirect to www.gnu.org/manual/
Links to using-utils.html #fragments are no longer correct as each utility
is now a separate page, since 646745cb.
indiana.edu seems to have moved XLiveCD information, without a redirect.
Linking to clean_setup.pl on cygwin.com doesn't work, as direct downloads
aren't allowed, so instead state where it can be found on a mirror.

Include ntsecapi.h where required and just redefine RtlGenRandom
correctly in the ntsecapi.h wrapper.

In preparation of exporting getentropy/getrandom to userspace, rearrange
code a bit:
- Define RtlGenRandom in ntdll.h.
- Drop calls to getentropy in favor of RtlGenRandom (fhandler_socket,
fhandler_dev_random).
- Add try/except blocks in fhandler_dev_random to return EFAULT rather
than crashing if buffer pointer is invalid.

NtOpenFile/NtCreateFile on non-existent paths on network drives has a
bug. Assuming a path Z:\dir\file. Further assuming that Z:\dir does
not exist.
The first NtOpenFile("Z:\dir\file") correctly returns
STATUS_OBJECT_PATH_NOT_FOUND. Subsequent calls incorrectly
return STATUS_OBJECT_NAME_NOT_FOUND.
This appears to be some kind of caching behaviour. Waiting a while
before repeating the call correctly returns STATUS_OBJECT_PATH_NOT_FOUND
again.
This patch works around the observed misbehaviour.

So far, when converting from POSIX to Windows notation, cygwin_conv_path
fails to check for .exe suffix, so /path/foo did not return /path/foo.exe
even if this file exists.

The original code only skipped the "./", but missed to test if more
trailing slashes are present. This in turn leads to invalid conversion.

Don't allow signal 0 in signal(2), sigaction(2), siginterrupt(3).
Don't allow any signal in sigqueue(3) but explicitely handle
signal 0 as in kill(2).

Provide <memory.h> for all standard Newlib targets and remove
Cygwin-specific header. Most POSIX like systems provide this historic

This makes it possible provide operating system specific types for
<pthread.h>. It is in line with the FreeBSD header file structure and
allows a future cleanup of <pthread.h> to not expose unrelated things
via <sys/types.h> and <unistd.h>. Glibc uses the similar
<bits/pthreadtypes.h> for this purpose.
