Fix RANDR’s gamma_to_ramp().

In order to generate a 256-entry ramp in [0,65535] which covers the full
range, one must mupliply eight-bit values not by 256 but rather by 257.

Many years back – well before the RANDR extension was written, and
before xorg@fdo – a similar bug fix was made to the DIX for converting
client-supplied eight-bit color values into sixteen-bit values.

os: Add CryptoAPI as a choice of SHA1 implementation

Both Cygwin and MinGW can use Windows' native CryptoAPI for SHA1,
saving a dependency on libgcrypt or OpenSSL. The necessary functions
are in ADVAPI32.DLL, which is among the default lib flags and is
already used in hw/xwin for accessing the registry.

configure.ac: on MinGW, link with ws2_32 instead of winsock2

ws2_32 is the correct name for the libary (even on 64 bit Windows :-))

configure.ac: MinGW doesn't have setuid binaries either.

If the target platform isn't in a list of platforms we know don't use a
setuid binary, we try to test if we can chown something to root.

This test possibly won't give the right answer if we are cross-compiling,
which is common for the MinGW target. This patch adds MinGW to the list
of platforms we know don't use a setuid binary.

configure.ac: auto-disable MITSHM if we lack IPC

The MITSHM extension uses SYSV IPC, but even if configure's test
for IPC failed, MITSHM was still enabled by default, breaking
MinGW builds by default.

Unfortunately, fixing this exposes the fact that the HAVE_SYSV_IPC
test wasn't being used for anything before and so we hadn't noticed it
was failing on Cygwin.

Change from using SHM_W|SHM_R flags (which aren't required by POSIX) to
S_IRUSR|S_IWUSR flags (which are)
