Fix a memory leak and release all dynamically allocated memory (ivlpp) This patch fixes a minor memory leak in ivlpp and releases all dynamically allocated memory before the program exits. Other than the dynamically allocated push state buffer in flex, ivlpp has no valgrind memory errors or warnings.

extern void reset_lexor(FILE*out, char*paths[]);
ivlpp - clear lexor dynamic state information for flex >= 2.5.9 For flex version 2.5.9 and later there is a function "yylex_destroy()" that clears any space dynamically allocated by the scanner.

Supoprt precompiled defines Core preprocessor support for writing out and reading precompiled defines. The preprocessor can read initial precompiled defines from any number of specified source files, and can write all the defines into a specified output file.

extern void load_precompiled_defines(FILE*src);
Add support for text macros with arguments. This patch modifies the preprocessor to handle text macros with arguments. It also fixes a bug that prevented a `line directive being issued after a multi-line text macro had been instantiated.

ivlpp: Removed the unnecessary parser The verilog preprocessing language is sufficiently simple that the parser may be implemented by hand on top of the lexical analyzer. In fact, ivlpp was already implemented in this way; relevant [bison] parser files specified no grammar, and the parser entry-point (yyparse) was simply an indirect use of the lexical analyzer (yylex). Therefore, parse.y has been removed, invocations of yyparse() have been replaced by yylex(), references to bison generated files have been removed, and Makefile.in has been updated accordingly.
