linux-user: Use `qemu_log' for non-strace logging

Browse Source 
Since most calls to `gemu_log` are actually logging unimplemented features,
this change replaces most non-strace calls to `gemu_log` with calls to
`qemu_log_mask(LOG_UNIMP, ...)`.  This allows the user to easily log to
a file, and to mask out these log messages if they desire.

Note: This change is slightly backwards incompatible, since now these
"unimplemented" log messages will not be logged by default.
