MD3: fix misaligned memory access
The memory subdivision was ordered such that this format likely had no
issues on a 32-bit machine but on 64-bit the alignment requirement of
texture_t increases to 8 bytes, invoking undefined behaviour.

Update and micro-optimise memory allocation
The max alignment requirement no longer needs to be hard-coded.
We were allocating slightly more than necessary for alignment padding.
Makes a (currently unused) macro more useful and robust.

Fix uses of strlcpy on unterminated source strings
BSD strlcpy() keeps reading until a \0 or a segfault, even after it
stops writing. In these cases the source was part of a longer string so
it wouldn't have crashed.
These were caught by the new warning.
The +1 on the source sizes copied an extra char that would be changed to
\0 and is now redundant because the real dest and src sizes are always
passed to a purpose-written func.

Compared to BSD strlcpy and strlcat, dp_strlcpy and dp_strlcat are
faster, never crash, and have a more useful return (DP didn't use the
strlcpy return at all), see included docs.
Adds dp_stpecpy() for efficient chain copying and dp_ustr2stp() for
copying measured byte sequences (unterminated strings) to strings.

sys: make stdout/stderr configurable during runtime
Adds cvar sys_stdout which offers the same behaviours as the -nostdout

Makes -noterminal cmdline option a synonym for -nostdout, previously it
was effectively the same but less efficient.

Changes to non-blocking stdout/stderr by default to prevent stutters and

(networking assumes at least 10).
If you want to save more resources, hide the game window (disables
rendering entirely) such as by using vid_minimize_on_focus_loss 1.
Disables cl_maxfps_alwayssleep by default, on modern systems with
accurate timers and higher FPS this has a significant impact.
Allows cl_maxfps_alwayssleep to be used with cl_maxfps 0, this was
requested some time ago.
Switches from cl_maxidlefps to cl_maxfps when querying servers to give
pings representative of what can be expected when playing on them.
Simplifies state tracking, ping is now either valid or not set (0) and
isn't abused to store state.
Includes a hash-verified timestamp in pings, fixes impossible pings
(happened when querytime was updated before response arrived) and the
ability to add servers to a client's list with unsolicited packets
(abusing the LAN support).
Checks that DP/QW master server list packets originate from a configured
master (cvar net_sourceaddresscheck).
Fixes unreliable LAN support.
Significantly reduces the total time to complete a full query cycle for
DP servers by improving the logic as well as turning up some cvars.
Prints warnings if DP or QW master server queries time out.
Makes net_slist_maxtries actually give better ping reports like its
description says.
Makes net_slist_pause completely pause (QC builtin resorthostcache()
used by Xonotic and Nexuiz bypassed it), clarifies description, uses a
callback instead of polling to handle changes.
Changes sv_masters[] and sv_qwmasters[] iteration to a more idiomatic
pattern pattern (numeric limit instead of a "null cvar" terminator).
Checks that sockets are open before writing to them in
NetConn_QueryQueueFrame() to avoid crashing in case we ever close a
lower numbered socket while a higher numbered one is still open.
Separates QW master list parsing into a func (like DP list parsing).
