Pedro Alves b3f11165aa Centralize yacc interface names remapping (yyparse, yylex, yyerror, etc)
This factors out all the yy-variables remapping to a single file,
instead of each parser having to do the same, with different prefixes.

With this, a parser just needs to define the prefix they want and
include yy-remap.h, which does the dirty job.

Note this renames the c_error, ada_error, etc. functions.  Writing the
remapping pattern as:

 #define yyerror GDB_YY_REMAP (error)

instead of:

 #define yyerror GDB_YY_REMAP (yyerror)

would have avoided the renaming.  However, that would be problematic
if we have a macro 'foo' in scope, when we write:

 #define yyfoo GDB_YY_REMAP (foo)

as that would expand 'foo'.

The c_yyerror etc. naming end ups indicating that this is a yacc
related function more clearly, so feels like a good change, anyway.
