Peter Maydell 24537a0191 qemu-log: Rename the public-facing cpu_set_log function to qemu_set_log
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().

Peter Maydell 59a6fa6e67 qemu-log: Abstract out "print usage message about valid log categories"
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

Andreas Färber 77868120cf linux-user: bsd-user: Don't reset X86CPU twice
Since commit 65dee38052 (target-i386:
move cpu_reset and reset callback to cpu.c) the x86 CPU is reset through
cpu_init() but was still reset immediately after in linux-user and
bsd-user. Clean this up.

Similarly in linux-user/syscall.c it is also reset after cpu_copy().
But that's a bug of its own, fixing which poses a semantic change.

Peter Maydell c8057f951d Support 'help' as a synonym for '?' in command line options
For command line options which permit '?' meaning 'please list the
permitted values', add support for 'help' as a synonym, by abstracting
the check out into a helper function.

This change means that in some cases where we were being lazy in
our string parsing, "?junk" will now be rejected as an invalid option
rather than being (undocumentedly) treated the same way as "?".

Update the documentation to use 'help' rather than '?', since '?'
is a shell metacharacter and thus prone to fail confusingly if there
is a single character filename in the current working directory and
the '?' has not been escaped. It's therefore better to steer users
towards 'help', though '?' is retained for backwards compatibility.

We do not, however, update the output of the system emulator's -help
(or any documentation autogenerated from the qemu-options.hx which
is the source of the -help text) because libvirt parses our -help
output and will break. At a later date when QEMU provides a better
interface so libvirt can avoid having to do this, we can update the
-help text too.

Peter Maydell d6ef40bf18 bsd-user: fix compile failure
bsd-user doesn't actually support reserving a memory area for the
guest address space, but we need to at least define the reserved_va
global so that cpu-all.h's RESERVED_VA macro will work correctly.

This fixes a compilation error introduced in commit 39879bb
which added a use of RESERVED_VA to h2g_valid().

has to come before the check for "not enough arguments", so that
"qemu-foo -d ?" prints the list of possible debug log items rather than
