Except for removing periods and exclamation points, no other changes
were made to the error messages (yet).
Backports relevant parts of commit 8afb900030b93122a40ef4a636d02ba888bdce12 from qemu
Straightforward replacement, except for qemu_kill_report(), which
printed a common part of its error message first, then the applicable
special part. Print each complete message with a single
error_report() instead.
Multi-line messages were replaced by error_report() followed by
error_printf().
The following changes were made to the error messages:
* The "invalid date format" message was reworded to better fit
the new error_report()+error_printf() pattern.
* On the remaining messages, only the trailing newlines, "qemu:" and
"error:" message prefixes were removed.
Backports relevant parts of commit f61eddcb2bb5cbbdd1d911b7e937db9affc29028 from qemu
Introduce a new crypto/ directory that will (eventually) contain
all the cryptographic related code. This initially defines a
wrapper for initializing gnutls and for computing hashes with
gnutls. The former ensures that gnutls is guaranteed to be
initialized exactly once in QEMU regardless of CLI args. The
block quorum code currently fails to initialize gnutls so it
only works by luck, if VNC server TLS is not requested. The
hash APIs avoids the need to litter the rest of the code with
preprocessor checks and simplifies callers by allocating the
correct amount of memory for the requested hash.

ARM and probably the rest of the arches have significant memory leaks as
they have no release interface.
Additionally, DrMemory does not have 64-bit support and thus I can't
test the 64-bit version under Windows. Under Linux valgrind supports
both 32-bit and 64-bit but there are different macros and code for Linux
and Windows.
