Fix bug in lexer_next_number not correctly tracking character number
...
Validate the build / validate-build (push) Successful in 28s
When a number has a suffix the lexer state didn't record the number of
characters consumed for this suffix. This made the lexer state be 2-3
characters short in its line location reporting until it encountered a
newline character. It did not otherwise corrupt the state of the lexer.

- Name all errors err_modulename_* for errors that belong to a specific
module and err_* for generic errors.

Rework the build system to be more modular

Split most of the work off into make/base.mk and allow for easy wrappers
to be created around that that can build with different instrumentation
in their own build directory.
Create wrappers for the following:
- release build
- debug build
- afl++ fuzzing build
- static analysis with clang
- clang memory sanitizer
- clang address/undefined sanitizer

Fix incorrect size comparison in lexer_consume_n
...
The buffer length len and the requested number of tokens n are mixed up
in an invalid comparison. This causes all valid requests for n < len
tokens to be denied and all invalid requests for n > len tokens to be
accepted. This may cause a buffer overflow if the caller requests more
characters than they provide space for.
