Move from flat mux/src/ layout to clean component hierarchy:
- mux/ is now the autoconf/automake build root (configure.ac lives here)
- mux/include/ — shared headers used by multiple components
- mux/lib/ — libmux.so (core utilities, no game state)
- mux/src/ — netmux driver only (thin networking shell)
- mux/modules/engine/ — engine.so (game logic)
- mux/modules/{comsys,mail,exp3,sqlproxy,sqlslave}/ — external modules
- mux/ganl/ — GANL networking library
- mux/sqlite/ — SQLite amalgamation (builds libsqlite3.a)
- mux/announce/ — announce tool (was mux/src/tools/)
Build changes:
- SUBDIRS ordering: ganl sqlite lib src modules announce
- libmux.so gets -Wl,-soname,libmux.so; netmux links via -L -lmux
- engine.so links libsqlite3.a and libmux.so with -Wl,--no-undefined
- RPATH uses $ORIGIN for portable .so resolution
- Install hooks use absolute paths for game/bin symlinks
Bug fixes:
- engine.so mux_Register() now passes nullptr to mux_RegisterClassObjects
(matches all other modules; libmux already has the factory via dlsym)
- DbConvert() now calls pcache_init() before db_write, fixing a latent
crash (free(): invalid pointer) when exporting from SQLite databases
411/411 smoke tests pass.
