docs-rst: parse-headers.pl: cleanup the documentation
Keeping both rst and in-file documentation in sync can be harsh. So, simplify the script's internal documntation to a bare minimum, and add a mention to the ReST file with its full documentation. This way, a quick help is still available at the command line, while the complete one is maintained at the ReST format. As we won't be using pad2rst anymore, do a cleanup at the ReST file.

It is also capable of distinguish #define used for specifying a Linux

-The EXCEPTIONS_FILE contain two types of statements: B<ignore> or B<replace>.
-
-The syntax for the ignore tag is:
-
-=over 8
-
-ignore B<type> B<name>
-
-=back
-
-The B<ignore> means that it won't generate cross references for a
-B<name> symbol of type B<type>.
-
-The syntax for the replace tag is:
-
-=over 8
-
-replace B<type> B<name> B<new_value>
-
-=back
-
-The B<replace> means that it will generate cross references for a
-B<name> symbol of type B<type>, but, instead of using the default
-replacement rule, it will use B<new_value>.
-
-For both statements, B<type> can be either one of the following:
-
-=over 8
-
-=item B<ioctl>
-
-The ignore or replace statement will apply to ioctl definitions like:
-
-#define VIDIOC_DBG_S_REGISTER _IOW('V', 79, struct v4l2_dbg_register)
-
-=item B<define>
-
-The ignore or replace statement will apply to any other #define found
-at C_FILE.
-
-=item B<typedef>
-
-The ignore or replace statement will apply to typedef statements at C_FILE.
-
-=item B<struct>
-
-The ignore or replace statement will apply to the name of struct statements
-at C_FILE.
-
-=item B<enum>
-
-The ignore or replace statement will apply to the name of enum statements
-at C_FILE.
+The EXCEPTIONS_FILE contain two rules to allow ignoring a symbol or
+to replace the default references by a custom one.
-=item B<symbol>
-
-The ignore or replace statement will apply to the name of enum statements
-at C_FILE.
-
-
-For replace statements, B<new_value> will automatically use :c:type:
-references for B<typedef>, B<enum> and B<struct> types. It will use :ref:
-for B<ioctl>, B<define> and B<symbol> types. The type of reference can
-also be explicitly defined at the replace statement.
