The regular expression to parse trace event definitions assumed the
format string would be a simple double-quoted string. However, we now
use PRI?64 for portability which splits string literals. The regular
expression can disregard the format string entirely since simpletrace.py
never needs to use it.

The lower bits of base/limit registers is RO and shouldn't be zero
cleared on reset. This patch fixes it.
In fact, the default value of base/limit registers aren't specified
in the spec. And some bridges disable forwarding on reset instead of
zeroing base/limit registers.
So introduce one function to disable bridge forwarding so that
such bridges can use it. It will be used later.

Win32 does not support line-buffering, but it allows
unbuffered output.
Unbuffered output is a good approximation. For typical output
statements which usually end with '\n', it's even identical.
Buffered output is unusable for program traces because of

The LTTng UserSpace Tracer formerly used TPPROTO() and TPARGS() instead
of TP_PROTO() and TP_ARGS() like the kernel uses. This has been changed
so QEMU needs to follow.
I am not aware of a graceful way of making the transition but since no
one complained that the UST build is broken, it should be fine to just
switch over without compatibility for old UST headers. The newer UST
headers are shipping in distro packages so it is realistic to make this
change now.
