vmstate: Add suppot for field_exist() test

vmstate: add support for arrays of pointers
We need this to send arrays of timers
vmstate: remove const for put operations
In a later patch, we introduce pre_save() and post_save() functions.The whole point of that operation is to change things in the state.Without this patch, we have to remove the const qualifier in eachuse with a cast...
vmstate: add version_id argument to post_load
Fix sys-queue.h conflict for good
Problem: Our file sys-queue.h is a copy of the BSD file, but there aresome additions and it's not entirely compatible. Because of that, there havebeen conflicts with system headers on BSD systems. Some hacks have beenintroduced in the commits 15cc9235840a22c289edbe064a9b3c19c5f49896,...
Include sys-queue.h early to override system queue definitions on BSD

vmstate: add support for uint8_t equal
vmstate: add sensible arguments to vmstate_unregister()
vmsd alone is not enugh, because we can have several structs saved with the same description (vmsd).
vmstate: rename run_after_load() -> post_load()
This naming was used in kvm tree, and is easier to remember
vmstate: Add pre_load() hook
vmstate: Add pre/post_save() hooks
Remove SaveVM v2 support
In previosu series I remove v2 support for RAM (that was the version that wassupported when SaveVM v3 appeared). Now we can't load RAM for any image saved in SaveVM v2, we can as well remove SaveVM v2 entirely.
Note: That SaveVM RAM was at v2 when General SaveVM support went from v2 to v3 makes talking about versions confusing at least...

VMState: Fix sub-structs versioning
We can't check the version in a substruct, it is not stored anywhere
Add VMState support for variable sized arrays
This patch add supports for variable sized arrays whose size isanother field of the state.
Add VMState support for static sized buffers (uint_8)
This patch adds support for static sized buffer and typecheks that the buffer is right.
Add VMState support for int32_t check value
We read the saved value and check that it is less or equal than the onestored in the structure.
Add VMState support to run a function after load
Use return value from load_state() call back
Add vmstate_load() and vmstate_save() functions
New VMstate save/load infrastructure
This patch introduces VMState infrastructure, to convert the save/loadfunctions of devices to a table approach. This new approach has thefollowing advantages:- it is type-safe- you can't have load/save functions out of sync...
Add VMState support for pointers
This patch adds support for saving pointers to values
Add VMState support for arrays
This patch adds support for saving arrays inside the struct
Add VMState support for structs
This patch adds support for saving one VMStateDescription from otherVMStateDescription.
We read the saved value and check that it is the same that the oneis stored in the structure.
split do_loadvm() into do_loadvm() and load_vmstate()
do_loadvm() is now called from the monitor.load_vmstate() is called by do_loadvm() and when -loadvm command line is used.Command line don't have to play games with vmstop()/vmstart()

unify popen/fopen qemu wrappers

kill drives_table
First step cleaning up the drives handling. This one does nothing butremoving drives_table[], still it became seriously big.

fix segfault in setting migration speed
Hi,
Whoever wrote this migrate_set_speed function is totally stupid.
Any failed or completed migration keeps its state to allow probing ofmigration data, but has no associated file anymore. It is, thus,possible to crash qemu by calling migrate_set_speed after a migration...
replace bdrv_{get, put}_buffer with bdrv_{load, save}_vmstate
The VM state offset is a concept internal to the image format. Replacethe old bdrv_{get,put}_buffer method that require an index into theimage file that is constructed from the VM state offset and an offset...
exec-migration: handle EINTR in popen_get_buffer()

Fix by retrying on such a case.

net: re-name vc->fd_read() to vc->receive()
VLANClientState's fd_read() handler doesn't read from filedescriptors, it adds a buffer to the client's receive queue.
Re-name the handlers to make things a little less confusing.
