Make sure all brower terminal output is suppressed. In order
to do that, eschew the use of the python module web browser

with stdout/err redirected to /dev/null.

Argument parsing job result [V4]

The current Job object initialization is doing many setups at once,
 for example, it creates a new job results dir with an "id" file inside.
 It handles the sysinfo start, update the latest
 link, etc. Things that can be done later.

This changes allows split the initialization in subparts:
* _setup_job_results() - creates a new job results directory with an id inside.
* _update_latest_link() - update the "latest (symbolic) link" to the job results.
* _start_sysinfo() - start the system information module.
* _remove_job_results() - remove the current job results from the directory.

So when running tests that are not found, say `avocado run quuuux`
then the job results will be removed and the link for the previous
result (latest) is preserved. Everything else should work as it was before.

Instead of delaying the parsing of the test list to code that handles
the jobs, let's handle that early, and in the usual Python way, simply
by relying on argparse.

For other, possibly more complex command line requirements, custom code
can be written, but it should still be placed at the argparse level.

Some obvious, but AFAICT not yet existing tests, that check if when
using bad command line arguments, avocado exists with a proper status
code.

Also, a more complex command line behavior test that checks if avocado
errors out early, before it creates the job result directory.

GDB fixes

The path of the binary that is fed into the GDB commands file can be

The reason is that runtime GDB settings are set by the GDB plugin, and

It's a very frequent code pattern to look for a binary in the system
using find_command(), and, if no command is found, trap the exception
generated and return a fallback.

This adds a `default` parameter that makes it possible to follow that
pattern without code outside the function itself.

avocado.utils.process.find_command(): move from avocado.utils.process to avocado.utils.path

The reasons for the proposed move include:

1) Even though find_command() looks for executables, it doesn't really
   try to execute them as a living process.

2) The implementation looks for it in a $PATH like list, so, out of a
   possibly better choice, avocado.utils.path was chosen.

3) Other modules can use that functionality, but not the execution of
   process.

4) Avoid circular dependencies: this is actually the first motivation
   of the proposed change, and a true story with the GDB plugin/test.
   Since avocado.utils.process depends on avocado.gdb, this module
   can not use find_command() to look for gdb/gdbserver binaries.
