spot-x.7: new man page for common fine-tuning options

* src/bin/spot-x.cc, src/bin/man/spot-x.x: New files.
* src/bin/Makefile.am, src/bin/man/Makefile.am: Adjust.
* src/bin/man/ltl2tgba.x: Remove all fine-tuning options,
and make a reference spot spot-x (7).
* src/bin/common_setup.hh, src/bin/common_setup.cc: Add
a misc_argp_hidden version of the option, so that --help
and --version are not shown in the --help output used
by help2man to generate spot-x.7.
* src/bin/ltl2tgba.cc: Refer to spot-x.7.

-[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
-\fBscc\-filter\fR
-Set to 1 (the default) to enable SCC-pruning and acceptance
-simplification at the beginning of post-processing.  Transitions that
-are outside of accepting SCC are removed from accepting sets, except
-those that enter into an accepting SCC.  Set to 2 to remove even these
-entering transition from the accepting sets.  Set to 0 to disable this
-SCC-pruning and acceptance simpification pass.
-.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.
-.TP
-\fBsimul\fR
-Set to 0 to disable simulation-based reductions.  Set to 1 to use only
-direct simulation.  Set to 2 to use only reverse simulation.  Set to 3
-to iterate both direct and reverse simulations.  Set to 4 to apply
-only "don't care" direct simulation.  Set to 5 to iterate "don't care"
-direct simulation and reverse simulation.  The default is 3, except
-when option \fB\-\-low\fR is specified, in which case the default is
-1.
-.TP
-\fBsimul-limit\fR
-Can be set to a positive integer to cap the number of "don't care"
-transitions considered by the "don't care"-simulation algorithm.  A
-negative value (the default) does not enforce any limit.  Note that if
-there are \fIN\fR "don't care" transitions, the algorithm may
-potentially test 2^\fIN\fR configurations.
