zittrig-4/src/sdl, branch master

implement part 1 of the multi-protocol functionality: protocols

2017-03-09T12:51:18+00:00

this contains support for connecting via, and serving simultaneously via, any of the three protocols: latest, GPP and 1.1

alternate-1 means protocol 70 (GPP), alternate-2 means protocol 69 (1.1)

relevant cvars:
- net_alternateProtocols
- net_alt{1|2}port[6]
- sv_alt{1|2}master{1|...|5}
- sv_clAltProto{0|..|63}

request a visual with at least 1 alpha bit: add r_alphabits, defaulting to 1

2017-03-09T12:51:11+00:00

this is required for binary shaders

add missing trailing '\n's from strings to execute; add double quotes around substituted argument strings

2017-02-08T01:17:01+00:00

also transform trailing ';'s to '\n's

use system libraries more properly; introduce a dependency on Minizip

remove the USE_LOCAL_HEADERS option (it was broken anyway)
