Previous commit added QMP documentation to the qemu-monitor.hx
file, it's is a copy of this information.

While it's good to keep it near code, maintaining two copies of
the same information is too hard and has little benefit as we
don't expect client writers to consult the code to find how to
use a QMP command.

One of the most important missing feature in QMP today is its
supported commands documentation.

The plan is to make it part of self-description support, however
self-description is a big task we have been postponing for a
long time now and still don't know when it's going to be done.

In order not to compromise QMP adoption and make users' life easier,
this commit adds a simple text documentation which fully describes
all QMP supported commands.

This is not ideal for a number of reasons (harder to maintain,
text-only, etc) but does improve the current situation. To avoid at
least divering from the user monitor help and texi snippets, QMP bits
are also maintained inside qemu-monitor.hx, and hxtool is extended to
generate a single text file from them.

When a page with all identical bytes is transferred, it is counted
as a full page (TARGET_PAGE_SIZE) although only one byte is actually
sent. Fix this by changing ram_save_block() to return the number of
bytes sent instead of a boolean value. This makes bandwidth
estimation, and consequently downtime estimation, more precise.
