Improve signals and memory protection
- Document sigaction() - Simplify New Technology fork() code - Testing and many bug fixes for mprotect() - Distribute Intel Xed ILD in the amalgamation - Turn Xed enums into defines to avoid DWARF bloat - Improve polyfilling of SA_SIGINFO on BSDs and fix bugs - setpgid(getpid(), getpid()) on Windows will ignore CTRL-C - Work around issues relating to NT mappings being executable - Permit automatic executable stack override via `ape_stack_pf`
