Web links in the documentation are not properly displayed.
In the man pages web links look like:
Osnoise tracer documentation: < <https://www.kernel.org/doc/html/lat‐
est/trace/osnoise-tracer.html> >
On web pages the URL caption is the URL itself.
Convert tracer documentation links to RST anonymous hyperlink format
for better rendering. Use newer docs.kernel.org instead of
www.kernel.org/doc/html/latest for brevity.
After the change, the links in the man pages look like:
Osnoise tracer <https://docs.kernel.org/trace/osnoise-tracer.html>
On web pages the captions are the titles of the links.

Sphinx reports htmldocs errors:
Documentation/tools/rtla/common_options.rst:58: ERROR: Undefined substitution referenced: "threshold".
Documentation/tools/rtla/common_options.rst:88: ERROR: Undefined substitution referenced: "tool".
Documentation/tools/rtla/common_options.rst:88: ERROR: Undefined substitution referenced: "thresharg".

Documentation/tools/rtla/common_options.rst:98: ERROR: Undefined substitution referenced: "actionsperf".
Documentation/tools/rtla/common_options.rst:113: ERROR: Undefined substitution referenced: "tool".
common_*.rst files are snippets that are intended to be included by rtla
docs (rtla*.rst). common_options.rst in particular contains
substitutions which depend on other common_* includes, so building it
independently as reST source results in above errors.
Rename all common_*.rst files to common_*.txt to prevent Sphinx from
building these snippets as standalone reST source and update all include
references accordingly.

The basic functionality came with the consolidation; now hook up the
command line options, and add documentation and tests.

Add auto-analysis to timerlat hist, including the --no-aa option to
reduce overhead and --dump-task. --aa-only was not added as it is
already on timerlat top.

The '-t/-T' parameters seem to have been swapped:
-t/--trace[=file]: save the stopped trace
to [file|timerlat_trace.txt]
-T/--thread us: stop trace if the thread latency
is higher than the argument in us
Swap them back.
