c5dfd1fc5c Fetch BSD regex from GitHub at build time
Replace bundled Spencer regex with a fetch-regex build step that
clones https://github.com/garyhouston/regex.git, generates the
required .ih and regex.h headers via mkh, and copies the result
into sys/amiga/regex/.

Usage: make CROSS_TO_AMIGA=1 fetch-regex

The fetched sources are not tracked in git.

cb0b11be11 Add portable utilities for creating tiles, add AmigaFont to symbols
- bmp2iff_host: convert nhtiles.bmp to Amiga IFF tile files. Uses
  the AMIV UI palette in pens 0-15, remaining pens filled with tile
  colors sorted by frequency.
  Usage: bmp2iff_host -planes N input.bmp output.iff

- xpm2iff_host: convert XPM to IFF for tomb.iff (RIP screen).
  Adapted from xpm2iff.c, Copyright (c) 1995 Gregg Wonderly.

- Auto-select tiles32.iff (5 planes) or tiles16.iff (4 planes)
  based on screen color depth at runtime.

- Fix NO_GLYPH in amiv_lprint_glyph: return early to prevent
  blitting with uninitialised data (caused black spots).

- Add AmigaFont symbol set to dat/symbols for AMII text mode.
