Hi,
The following patches introduce the support of the dirty bitmap logging and
dumping to a specified file. This patch series addresses the previous issues
raised by David and Eric.
v5 --> v6
* The shared function between migration and log bitmap has been again modified
(David's advice).
* Again changed the naming conventions for shared state between migration and
log dirty bitmap (David's and Eric's advice).
* Removed acronyms (Eric's advice).
* Fixed grammatical mistakes and macros (Eric's advice).
* Modified the python script to utilize less memory as well as dump the snapshot
into a file instead of separate window (David's advice).
v4 --> v5
* Removed the runstates code (Eric's and David's advice).
* Now, using global variable to resolve the issue between migration and
bitmap dump (David's advice).
* Merged the hmp and qmp interface's patch (Eric's advice).
* Modified the code to support the dynamic change in last_ram_offset (David's
advice).
* Formatted the strings in the python code i.e. length followed by text
(David's advice).
* Added some code to generate black and white figure based on the bitmap.
* Modified the shared function to be more generic (David's advice).
v3 --> v4
* Added new qmp interface for information extraction from the bitmap process
v2 --> v3
* Reformatted the code and removed some unnecessary parts.
* Printing block info along with length and offset.
* Changed the functions that were directly using RUN_STATE_RUNNING as state.
v1 --> v2:
* Added two new run states to avoid simultaneous execution of both migration and
bitmap dump process.
* Removed FILE pointer usage.
* Dumping the data only in machine-readable format.
* Tried to rectify mistakes of the previous version.

generic function between migration and bitmap dump
BitmapLog: bitmap dump code
BitmapLog: get the information about the parameters
BitmapLog: cancel mechanism for an already running dump bitmap process
BitmapLog: set the period of the dump bitmap process
BitmapLog: python script for extracting bitmap from a binary file
