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.
