84d18f065f Use error_is_set() only when necessary
error_is_set(&var) is the same as var != NULL, but it takes
whole-program analysis to figure that out.  Unnecessarily hard for
optimizers, static checkers, and human readers.  Dumb it down to
obvious.

Gets rid of several dozen Coverity false positives.

Note that the obvious form is already used in many places.

ff9ec34de8 QMP: allow JSON dict arguments in qmp-shell
qmp-shell hides the QMP wire protocol JSON encoding from the user.  Most
of the time this is helpful and makes the command-line human-friendly.

Some QMP commands take a dict as an argument.  In order to express this
we need to revert back to JSON notation.

This patch allows JSON dict arguments in qmp-shell so commands like
blockdev-add and nbd-server-start can be invoked:

  (QEMU) blockdev-add options={"driver":"file","id":"drive1",...}

Note that spaces are not allowed since str.split() is used to break up
the command-line arguments first.

dde3a21840 hmp: migrate command (without -d) now blocks correctly
This patch fixes a timing issue that migrate command (without -d) does not
block in some cases.

The original version of hmp.c:hmp_migrate_status_cb checks if the
migration status is 'active' or not to detect the completion of a migration.

However, if this function is executed when the migration status is stil
'setup' (the status before 'active'), migration command returns
immediately even if the user does not specify -d option.

6399ab3325 tcg/i386: Use SHLX/SHRX/SARX instructions
These three-operand shift instructions do not require the shift count
to be placed into ECX.  This reduces the number of mov insns required,
with the mere addition of a new register constraint.

Don't attempt to get rid of the matching constraint, as that's impossible
to manipulate with just a new constraint.  In addition, constant shifts
still need the matching constraint.

46eef33b89 Fix QEMU build on OpenBSD on x86 archs
This resolves the build issue with building the ROMs on OpenBSD on x86 archs.
As of OpenBSD 5.3 the compiler builds PIE binaries by default and thus the
whole OS/packages and so forth. The ROMs need to have PIE disabled.
Check in configure whether the compiler supports the flags for disabling
PIE, and if it does then use them for building the ROMs. This fixes the
following buildbot failure:

5556332aba gitignore: anchor all ignored names
by default, patterns/names in .gitignore are applied
recursively to all subdirectories.  So any name mentioned
in .gitignore is ignored in all subdirectores.  This is good
for, say. object files (*.o), but not good for particular
names which should be ignored only in one directory.  For
example, qemu-img.1 file is generated in the top directory,
and it should be ignored only there, not in some subdir.

At first, this might not matter much, but we have lots of
examples already where it actually does not help at all.
For example, top-level .gitignore ignores a file/dir named
"patches" (which is very questionable by itself), but it
is applied recursively, so git also ignores, for example,
debian/patches/ which should not be ignored.

So anchor all the names where appropriate.  .gitignore
should be cleaned up further, which will be addressed in
a subsequent patch.

and they continue to carry lots of anymore-unused stuff.

Apparently there are more includes like this, because
many are included from qemu-common.h and the like, or,
for example, I don't see were we use win32-specific
stuff in vl.c (so that maybe #include <windows.h> might

e41b509d68 qapi: Refine human printing of sizes
This fixes several bugs or shortcomings of the previous pretty-printer.
In particular:

* use PRIu64 instead of casting to long long

* the exact value is included too

* the correct unit of measure (MiB, GiB, etc.) is used.  PiB and EiB
are added too.

* due to an off-by-one error, 512*2^30 was printed as 0.500MiB rather than
512MiB.  floor(log2(val)) is equal to 63 - clz(val), while the code used 64.

* The desired specification is %g rather than %f, which always uses three
decimals in the current code.  However %g would switch to scientific
notation when the integer part is >= 1000 (e.g. 1000*2^30).  To keep the
code simple, switch to the higher power when the integer part is >= 1000;
overflow is avoided by using frexp instead of clz.

Their functionality is either aesthetic only (e.g. on/off vs. true/false)

0b7593e085 qapi: Add human mode to StringOutputVisitor
This will be used by "info qtree".  For numbers it prints both the
decimal and hex values.  For sizes it rounds to the nearest power
of 2^10.  For strings, it puts quotes around the string and separates
NULL and empty string.
