Rather than creating stubs for every command that just return
QERR_UNSUPPORTED, use 'if' conditions in the schema to fully
exclude generation of the filesystem trimming commands on POSIX
platforms lacking required APIs.
The command will be rejected at QMP dispatch time instead,
avoiding reimplementing rejection by blocking the stub commands.
This changes the error message for affected commands from
{"class": "CommandNotFound", "desc": "Command FOO has been disabled"}
to
{"class": "CommandNotFound", "desc": "The command FOO has not been found"}
This has the additional benefit that the QGA protocol reference
now documents what conditions enable use of the command.

The qmp_guest_{set,get}_{memory_blocks,block_info} command impls in
commands-posix.c are surrounded by '#ifdef __linux__' so should
instead live in commands-linux.c
This also removes a "#ifdef CONFIG_LINUX" that was nested inside
a "#ifdef __linux__".

In the next patches we are going to add FreeBSD support for QEMU Guest
Agent. In the result, code in commands-posix.c will be too cumbersome.
Move Linux-specific FS freeze/thaw code to a separate file commands-linux.c
keeping common POSIX code in commands-posix.c.
