machine: Eliminate QEMUMachine and qemu_register_machine()
The struct is not used anymore and can be eliminated.

machine: Set MachineClass::name automatically
Now all TYPE_MACHINE subclasses use MACHINE_TYPE_NAME to generate the
class name. So instead of requiring each subclass to set
MachineClass::name manually, we can now set it automatically at the
TYPE_MACHINE class_base_init() function.

machine: MACHINE_TYPE_NAME macro
The macro will be useful to ensure the machine class names follow the
right format to make machine class lookup by class name work correctly.

machine: Remove unused fields from QEMUMachine
This removes the following fields from QEMUMachine: family, alias,
reset, hot_add_cpu, units_per_default_bus, no_serial, no_parallel,
use_virtcon, use_sclp, no_floppy, no_cdrom, default_display,
compat_props, and hw_version.

The only users of those fields were already converted to use QOM and
MachineClass directly, so they are not needed anymore.

Include qapi/error.h exactly where needed
This cleanup makes the number of objects depending on qapi/error.h
drop from 1910 (out of 4743) to 1612 in my "build everything" tree.

While there, separate #include from file comment with a blank line,
and drop a useless comment on why qemu/osdep.h is included first.

util: add cacheinfo
Add helpers to gather cache info from the host at init-time.

For now, only export the host's I/D cache line sizes, which we
will use to improve cache locality to avoid false sharing.

tcg: add options for enabling MTTCG
We know there will be cases where MTTCG won't work until additional work
is done in the front/back ends to support. It will however be useful to
be able to turn it on.

As a result MTTCG will default to off unless the combination is
supported. However the user can turn it on for the sake of testing.

cpu: Support a target CPU having a variable page size
Support target CPUs having a page size which isn't knownn
at compile time. To use this, the CPU implementation should:
* define TARGET_PAGE_BITS_VARY
* not define TARGET_PAGE_BITS
* define TARGET_PAGE_BITS_MIN to the smallest value it
might possibly want for TARGET_PAGE_BITS
* call set_preferred_target_page_bits() in its realize
function to indicate the actual preferred target page
size for the CPU (and report any error from it)

In CONFIG_USER_ONLY, the CPU implementation should continue
to define TARGET_PAGE_BITS appropriately for the guest
OS page size.

Machines which want to take advantage of having the page
size something larger than TARGET_PAGE_BITS_MIN must
set the MachineClass minimum_page_bits field to a value
which they guarantee will be no greater than the preferred
page size for any CPU they create.

Note that changing the target page size by setting
minimum_page_bits is a migration compatibility break
for that machine.

For debugging purposes, attempts to use TARGET_PAGE_SIZE
before it has been finally confirmed will assert.

util: move declarations out of qemu-common.h
Move declarations out of qemu-common.h for functions declared in
utils/ files: e.g. include/qemu/path.h for utils/path.c.
Move inline functions out of qemu-common.h and into new files (e.g.
include/qemu/bcd.h)

vl.c: Remove periods and exclamation points from error messages
Except for removing periods and exclamation points, no other changes

vl.c: Replace fprintf(stderr) with error_report()
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.

crypto: introduce new module for computing hash digests
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.

farmdve 036763d6ae Fix memory leaks as reported by DrMemory and Valgrind.
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.
