New FGCom standalone re-wrote from scratch

Browse source 
- positions.txt and special.txt are integrated in the binary
- Reduce CPU load
- New mode: OBS for listening a frequency
- Source code ready to be used with another library
- Support for COM1 and COM2
- Fix bug where frequencies conflict avoid switching between similar frequency in range
- Better logging information and debug information
- Range depends on altitude

The LONG_OPTIONS argument to getopt_long or getopt_long_only is a vector

zero.
The field `has_arg' is:
no_argument (or 0) if the option does not take an argument,
required_argument (or 1) if the option requires an argument,
optional_argument (or 2) if the option takes an optional argument.
If the field `flag' is not NULL, it points to a variable that is set
to the value given in the field `val' when the option is found, but
left unchanged if the option is not found.
To have a long-named option do something other than set an `int' to
a compiled-in constant, such as set a value from `optarg', set the
option's `flag' field to zero and its `val' field to a nonzero
value (the equivalent single-letter option character, if there is
one). For long options that have a zero `flag' field, `getopt'
returns the contents of the `val' field. */

Return the option character from OPTS just read. Return -1 when
there are no more options. For unrecognized options, or options
missing arguments, `optopt' is set to the option letter, and '?' is
returned.
The OPTS string is a list of characters which are recognized option
letters, optionally followed by colons, specifying that that letter
takes an argument, to be placed in `optarg'.
If a letter in OPTS is followed by two colons, its argument is
optional. This behavior is specific to the GNU `getopt'.
The argument `--' causes premature termination of argument
scanning, explicitly telling `getopt' that there are no more
options.
If OPTS begins with `--', then non-option arguments are treated as
arguments to the option '\0'. This behavior is specific to the GNU
