Clean up includes so that osdep.h is included first and headers
which it implies are not included manually.

This commit was created with scripts/clean-includes.

Daniel P. Berrange 10817bf09d coroutine: move into libqemuutil.a library
The coroutine files are currently referenced by the block-obj-y
variable. The coroutine functionality though is already used by
more than just the block code. eg migration code uses coroutine
yield. In the future the I/O channel code will also use the
coroutine yield functionality. Since the coroutine code is nicely
self-contained it can be easily built as part of the libqemuutil.a
library, making it widely available.

The headers are also moved into include/qemu, instead of the
include/block directory, since they are now part of the util
codebase, and the impl was never in the block/ directory
either.

Markus Armbruster 97f3ad3551 migration: Use g_new() & friends where that makes obvious sense
g_new(T, n) is neater than g_malloc(sizeof(T) * n).  It's also safer,
for two reasons.  One, it catches multiplication overflowing size_t.
Two, it returns T * rather than void *, which lets the compiler catch
more type errors.

This commit only touches allocations with size arguments of the form
sizeof(T).  Same Coccinelle semantic patch as in commit b45c03f.

Dr. David Alan Gilbert a202a4c001 migration: size_t'ify some of qemu-file
This is a start on using size_t more in qemu-file and friends;
it fixes up QEMUFilePutBufferFunc and QEMUFileGetBufferFunc
to take size_t lengths and return ssize_t return values (like read(2))
and fixes up all the different implementations of them.

Note that I've not yet followed this deeply into bdrv_ implementations.

migrate_rdma_pin_all() and qsb_clone() are completely unused and thus
can be deleted.

Yang Hongyang f018d8cd21 QEMUSizedBuffer: only free qsb that qemu_bufopen allocated
Only free qsb that qemu_bufopen allocated, and also allow
qemu_bufopen accept qsb as input for write operation. It
will make the API more logical:
1.If you create the QEMUSizedBuffer yourself, you need to
  free it by using qsb_free() but not depends on other API
  like qemu_fclose.
2.allow qemu_bufopen() accept QEMUSizedBuffer as input for
  write operation, otherwise, it will be a little strange
  for this API won't accept the second parameter.

This brings API change, since there are only 3
users of this API currently, this change only impact the
first one which will be fixed in patch 2 of this patchset,
so I think it is safe to do this change.

1     70  tests/test-vmstate.c <<open_mem_file_read>>
            return qemu_bufopen("r", qsb);
2    404  tests/test-vmstate.c <<test_save_noskip>>
            QEMUFile *fsave = qemu_bufopen("w", NULL);
3    424  tests/test-vmstate.c <<test_save_skip>>
            QEMUFile *fsave = qemu_bufopen("w", NULL);

The splitting of qemu-file and addition of the buffered file landed
at the same time; so now split the buffered file code out.
