scripts/qemu-trace-stap: Convert documentation to rST

The qemu-trace-stap documentation is currently in
scripts/qemu-trace-stap.texi in Texinfo format, which we
present to the user as:
 * a qemu-trace-stap manpage
 * but not (unusually for QEMU) part of the HTML docs

Convert the documentation to rST format that lives in
the docs/ subdirectory, and present it to the user as:
 * a qemu-trace-stap manpage
 * part of the interop/ Sphinx manual

There are minor formatting changes to suit Sphinx, but no
content changes.

-@example
-@c man begin SYNOPSIS
-@command{qemu-trace-stap} @var{GLOBAL-OPTIONS} @var{COMMAND} @var{COMMAND-OPTIONS} @var{ARGS...}
-@c man end
-@end example
-
-@c man begin DESCRIPTION
-
-The @command{qemu-trace-stap} program facilitates tracing of the execution
-of QEMU emulators using SystemTap.
-
-It is required to have the SystemTap runtime environment installed to use
-this program, since it is a wrapper around execution of the @command{stap}
-program.
-
-@c man end
-
-@c man begin OPTIONS
-
-The following global options may be used regardless of which command
-is executed:
-
-@table @option
-@item @var{--verbose}, @var{-v}
-
-Display verbose information about command execution.
-
-@end table
-
-The following commands are valid:
-
-@table @option
-
-@item @var{list} @var{BINARY} @var{PATTERN...}
-
-List all the probe names provided by @var{BINARY} that match
-@var{PATTERN}.
-
-If @var{BINARY} is not an absolute path, it will be located by searching
-the directories listed in the @code{$PATH} environment variable.
-
-@var{PATTERN} is a plain string that is used to filter the results of
-this command. It may optionally contain a @code{*} wildcard to facilitate
-matching multiple probes without listing each one explicitly. Multiple
-@var{PATTERN} arguments may be given, causing listing of probes that match
-any of the listed names. If no @var{PATTERN} is given, the all possible
-probes will be listed.
-
-For example, to list all probes available in the @command{qemu-system-x86_64}
-binary:
-
-@example
-$ qemu-trace-stap list qemu-system-x86_64
-@end example
-
-To filter the list to only cover probes related to QEMU's cryptographic
-subsystem, in a binary outside @code{$PATH}
-
-@example
-$ qemu-trace-stap list /opt/qemu/4.0.0/bin/qemu-system-x86_64 'qcrypto*'
-@end example
-
-
-@item @var{run} @var{OPTIONS} @var{BINARY} @var{PATTERN...}
-
-Run a trace session, printing formatted output any time a process that is
-executing @var{BINARY} triggers a probe matching @var{PATTERN}.
-
-If @var{BINARY} is not an absolute path, it will be located by searching
-the directories listed in the @code{$PATH} environment variable.
-
-@var{PATTERN} is a plain string that matches a probe name shown by the
-@var{list} command. It may optionally contain a @code{*} wildcard to
-facilitate matching multiple probes without listing each one explicitly.
-Multiple @var{PATTERN} arguments may be given, causing all matching probes
-to be monitored. At least one @var{PATTERN} is required, since stap is not
-capable of tracing all known QEMU probes concurrently without overflowing
-its trace buffer.
-
-Invocation of this command does not need to be synchronized with
-invocation of the QEMU process(es). It will match probes on all
-existing running processes and all future launched processes,
-unless told to only monitor a specific process.
-
-Valid command specific options are:
-
-@table @option
-@item @var{--pid=PID}, @var{-p PID}
-
-Restrict the tracing session so that it only triggers for the process
-identified by @code{PID}.
-
-@end table
-
-For example, to monitor all processes executing @command{qemu-system-x86_64}
-as found on $PATH, displaying all I/O related probes:
-
-@example
-$ qemu-trace-stap run qemu-system-x86_64 'qio*'
-@end example
-
-To monitor only the QEMU process with PID 1732
-
-@example
-$ qemu-trace-stap run --pid=1732 qemu-system-x86_64 'qio*'
-@end example
-
-To monitor QEMU processes running an alternative binary outside of
-@code{$PATH}, displaying verbose information about setup of the
-tracing environment:
-
-@example
-$ qemu-trace-stap -v run /opt/qemu/4.0.0/qemu-system-x86_64 'qio*'
-@end example
-
