tcg/arm: remove fixed map code buffer restriction

On ARM, don't map the code buffer at a fixed location, and fix up the
call/goto tcg routines to let it do long jumps.

Mapping the code buffer at a fixed address could sometimes result in it being
mapped over the top of the heap with pretty random results.

target-i386: fix cmpxchg instruction emulation

When the i386 cmpxchg instruction is executed with a memory operand
and the comparison result is "unequal", do the memory write before
changing the accumulator instead of the other way around, because
otherwise the new accumulator value will incorrectly be used in the
comparison when the instruction is restarted after a page fault.

w32: Disable buffering for log file

W32 does not support line buffering, but it supports unbuffered output.

Unbuffered output is better for writing to qemu.log than fully buffered
output because it also shows the latest log messages when an application
crash occurs.

w32: QEMU applications with SDL are always GUI applications

Since commit 1d14ffa97eacd3cb722271eaf6f093038396eac4 (in 2005),
QEMU applications on W32 don't use the default SDL compiler flags:

Instead of a GUI application, a console application is created.

This has disadvantages (there is always an empty console window) and
no obvious reason, so this patch removes the strange flag modification.

The SDL GUI applications still can be run from a console window
and even send stdout and stderr to that console by setting environment
variable SDL_STDIO_REDIRECT=no.

qapi: Convert blockdev_snapshot_sync

Unfortunately, this conversion required an additional change.

In the old QMP command, the 'snapshot-file' argument is specified as
optional. The idea is to take the snapshot internally if 'snapshot-file'
is not passed. However, internal snapshots are not supported yet so
the command returns a MissingParamater error if 'snapshot-file' is not
passed. Which makes the argument actually required and will cause
compatibility breakage if we change that in the future.

To fix this the QAPI converted blockdev_snapshot_sync command makes the
'snapshot-file' argument required. Again, in practice it's actually required,
so this is not incompatible.

If we do implement internal snapshots someday, we'll need a new argument
for it.

Note that this discussion doesn't affect HMP.

configure: Don't mix glib and libcheck tests

test-coroutine is listed as a libcheck test in the 'checks' variable. This
is not right because 'make check' won't run test-coroutine if libcheck
tests are not enabled (either because libcheck isn't detected or because
--disable-check-utests is passed).

Tests using the glib test framework are independent from libcheck and
afaik are always present (although having a configure switch to disable
them is probably worth it).

Untangle test-coroutine from the libcheck tests by introducing the
'test_progs' variable and using it to generate the test list used by
'make check'.

qmp: add test tool for QMP

Anthony wrote this quickly to aid in testing.  It's similar to qmp-shell with
a few important differences:

1) It is not interactive.  That makes it useful for scripting.

2) qmp-shell:

(QEMU) set_password protocol=vnc password=foo

3) qmp:

$ qmp set_password --protocol=vnc --password=foo

4) Extensible, git-style interface.  If an invalid command name is
passed, it will try to exec qmp-$1.

5) It attempts to pretty print the JSON responses in a shell friendly
format such that tools can work with the output.

Hope others will also find it useful.
