more mostly pointless file shuffling

- merge headers (except adivtab.h, anorms.h, rand1k.h) → dat.h, fns.h and
  game/game.h. game.h remains for mod shit
- remove const qualifiers (mostly from menu stuff)
- put TARG in mk.$game for setting binary's name for each mod
- plan9-ish C style for some files

-KEY BUTTONS
-
-Continuous button event tracking is complicated by the fact that two different
-input sources (say, mouse button 1 and the control key) can both press the
-same button, but the button should only be released when both of the
-pressing key have been released.
-
-When a key event issues a button command (+forward, +attack, etc), it appends
-its key number as a parameter to the command so it can be matched up with
-the release.
-
-state bit 0 is the current state of the key
-state bit 1 is edge triggered on the up to down transition
-state bit 2 is edge triggered on the down to up transition

+only used during filesystem initialization.
+
+The "game directory" is the first tree on the search path and directory that all generated files (savegames, screenshots, demos, config files) will be saved to.  This can be overridden with the "-game" command line parameter.  The game directory can never be changed while quake is executing.

+packet header
+-------------
+31	sequence
+1	does this message contain a reliable payload
+31	acknowledge sequence
+1	acknowledge receipt of even/odd message
+16	qport
+
+The remote connection never knows if it missed a reliable message, the
+local side detects that it has been dropped by seeing a sequence acknowledge
+higher thatn the last reliable sequence, but without the correct evon/odd
+bit for the reliable set.
+
+If the sender notices that a reliable message has been dropped, it will be
+retransmitted.  It will not be retransmitted again until a message after
+the retransmit has been acknowledged and the reliable still failed to get there.
+
+if the sequence number is -1, the packet should be handled without a netcon
+
+The reliable message can be added to at any time by doing
+MSG_Write* (&netchan->message, <data>).
+
+If the message buffer is overflowed, either by a single message, or by
+multiple frames worth piling up while the last reliable transmit goes
+unacknowledged, the netchan signals a fatal error.
+
+Reliable messages are always placed first in a packet, then the unreliable
+message is included if there is sufficient room.
+
+To the receiver, there is no distinction between the reliable and unreliable
+parts of the message, they are just processed out as a single larger message.
+
+Illogical packet sequence numbers cause the packet to be dropped, but do
+not kill the connection.  This, combined with the tight window of valid
+reliable acknowledgement numbers provides protection against malicious
+address spoofing.
+
+
+The qport field is a workaround for bad address translating routers that
+sometimes remap the client's source port on a packet during gameplay.
+
+If the base part of the net address matches and the qport matches, then the
+channel matches even if the IP port differs.  The IP port should be updated
+to the new value before sending out any replies.
+
+
+If there is no information that needs to be transfered on a given frame,
+such as during the connection stage while waiting for the client to load,
+then a packet only needs to be delivered if there is something in the
+unacknowledged reliable

-The "base directory" is the path to the directory holding the quake.exe and all game directories.  The sys_* files pass this to host_init in quakeparms_t->basedir.  This can be overridden with the "-basedir" command line parm to allow code debugging in a different directory.  The base directory is
-only used during filesystem initialization.
-
-The "game directory" is the first tree on the search path and directory that all generated files (savegames, screenshots, demos, config files) will be saved to.  This can be overridden with the "-game" command line parameter.  The game directory can never be changed while quake is executing.  This is a precacution against having a malicious server instruct clients to write files over areas they shouldn't.
