postproc: Add an option_map parameter

Browse source 
* src/tgbaalgos/postproc.cc: Add an option_map parameter, and use to get
extra options to pass to the degeneralization algorithm.
* src/tgbaalgos/postproc.hh: Adjust prototype, and store Boolean
variables for degeneralize() options.
* src/bin/ltl2tgba.cc: Add a -x option to fill the option map, and pass
it to the postprocessor.
* src/bin/man/ltl2tgba.x: Document the three degeneralization options.

[DESCRIPTION]
.\" Add any additional description here
[FINE-TUNING OPTIONS]
The \fB\-\-extra\-options\fR argument is a comma-separated list of
\fIKEY\fR=\fIINT\fR assignments that are passed to the post-processing
routines (they may be passed to other algorithms in the future).
These options are mostly used for benchmarking and debugging
purpose. \fIKEY\fR (without any value) is a
shorthand for \fIKEY\fR=1, and !\fIKEY\fR is a shorthand for
\fIKEY\fR=0.
Supported options are:
.TP
\fBdegen\-reset\fR
If non-zero (the default), the degeneralization algorithm will reset
its level any time it exits a non-accepting SCC.
.TP
\fBdegen\-lcache\fR
If non-zero (the default), whenever the degeneralization algorithm enters
an SCC on a state that has already been associated to a level elsewhere,
it should reuse that level. The "lcache" stands for "level cache".
.TP
\fBdegen\-order\fR
If non-zero, the degeneralization algorithm will compute one degeneralization
order for each SCC it processes. This is currently disabled by default.
