Switch the default for qemu_log logging output from "/tmp/qemu.log"
to stderr. This is an incompatible change in some sense, but logging
is mostly used for debugging purposes so it shouldn't affect production
use. The previous behaviour can be obtained by adding "-D /tmp/qemu.log"
to the command line.
This change requires us to:
* update all the documentation/help text (we take the opportunity
to smooth out minor inconsistencies between the phrasing in
linux-user/bsd-user/system help messages)
* make linux-user and bsd-user defer to qemu-log for the default
logging destination rather than overriding it themselves
* ensure that all logfile closing is done via qemu_log_close()
and that that function doesn't close stderr
as well as the obvious change to the behaviour of do_qemu_set_log()
when no logfile name has been specified.

Remove the function qemu_log_try_set_file() and its users (which
are all in TCG code generation functions for various targets).
This function was added to abstract out code which was originally
written as "if (!logfile) logfile = stderr;" in order that BUG:
case code which did an unguarded "fprintf(logfile, ...)" would
not crash if debug logging was not enabled. Since those direct
uses of logfile have also been abstracted away into qemu_log()
calls which check for a NULL logfile, there is no need for the
target-* files to mess with the user's chosen logging settings.

Rename the typedef CPULogItem and the public array cpu_log_items
to names that better reflect the fact that the qemu_log functionality
isn't restricted to TCG CPU debug logs any more.

Rename the public-facing function cpu_set_log to qemu_set_log. This
requires us to rename the internal-only qemu_set_log() to
do_qemu_set_log().

the qemu_log functionality is no longer restricted to TCG CPU

Abstract out the "print a human readable list of all the
valid log categories" functionality which is currently duplicated
in three separate places. (We leave the monitor.c help_cmd()
implementation as-is since it wants to send the message to
the monitor and add its own information.)

The qemu_log() functionality is no longer specific to TCG CPU debug logs.
Rename cpu_set_log_filename() to qemu_set_log_filename() and drop the
pointless wrapper set_cpu_log_filename().
