94ac5cd20c monitor: Prevent sign-extension of 32-bit addresses printed by info tlb 
This is the same fix that was recently applied to info mem.  Before
this change, info tlb output looked like:

ffffffffffffc000: 000000000fffc000 --------W
ffffffffffffd000: 000000000fffd000 --------W
ffffffffffffe000: 000000000fffe000 --------W
fffffffffffff000: 000000000ffff000 --------W

With this change, it looks like

00000000ffffc000: 000000000fffc000 --------W
00000000ffffd000: 000000000fffd000 --------W
00000000ffffe000: 000000000fffe000 --------W

25c4d9cc84 tcg: Always define all of the TCGOpcode enum members. 
By always defining these symbols, we can eliminate a lot of ifdefs.

To allow this to be checked reliably, the semantics of the
TCG_TARGET_HAS_* macros must be changed from def/undef to true/false.
This allows even more ifdefs to be removed, converting them into
C if statements.

b49ca72dd7 monitor: Prevent sign-extension of 32-bit addresses printed by info mem 
Previously, on 32-bit i386, info mem used signed 32-bit int's to store
the page table indexes.  As a result, address calculation was done in
32 bits and then incorrectly sign-extended to 64 bits, yielding output
like

ffffffffef000000-ffffffffef031000 0000000000031000 ur-
ffffffffef7bc000-ffffffffef7bd000 0000000000001000 urw
ffffffffef7bd000-ffffffffef7be000 0000000000001000 ur-

This makes these indexes unsigned, which yields correct output

00000000ef000000-00000000ef031000 0000000000031000 ur-
00000000ef7bc000-00000000ef7bd000 0000000000001000 urw

3feaca9e88 Fix conversions from pointer to tcg_target_long 
tcg_gen_exit_tb takes a parameter of type tcg_target_long,
so the type casts of pointer to long should be replaced by
type casts of pointer to tcg_target_long.

These changes are needed for build environments where
sizeof(long) != sizeof(void *), especially for w64.

See 4b4a72e556 which fixed the
same issue for the other targets.

similar define in system include files. In particular the
Ubuntu Lucid SPARC signal.h will define REG_PC, and since
qemu-common.h now includes signal.h this was causing compile
failures. Rename the constants to avoid this issue.

83b2f0a0d8 configure: Disable guest_agent for mingw32 
guest_agent is not supported for mingw32, so the default value
should be 'no', not 'yes'.

This removes the dependencies to glib-2.0 and python which
makes native and cross builds for w32 much easier (no need
to get and install these extra packages).

It also avoids the problems caused by different bitfield alignment
which is required by glib-2.0.

It is still possible to set guest_agent=yes via configure option.
