53d8cb67ba Set monitor connections to non-blocking
Better to just drop monitor connections when the quality is bad than to
risk blocking the shard thread.

6b257887b7 Use an std::vector for PollFDs instead of handling it manually
Lowered poll() timeout to 50, to fix (work around?) slider stutter.

ec7cba644c Clean up polling logic
* Extracted PollFD manipulation and nonblocking socket configuration
into helper functions
* Replaced the connections list with an unordered_map
* Dynamically grow the number of PollFD structures with realloc()

With these changes done, the server's CPU usage is completely diminished
from its old average of ~47% to ~0.07%, with occasional spikes up to ~14%.

e03da83ff3 Rearranged the codebase a little.
* Deleted empty Player.cpp
* Moved the helper functions from the obsolete CNStructs.cpp into
main.cpp and deleted it
* Renamed CombatManager to MobManager, as that will likely become it's
main focus soon

131997f34f Cleaned up all whitespace issues.
The incantation was: sed -i 's/[ \t]*$//g' src/*.[ch]pp

67d899efe6 Implemented proper validation of variable-length packets.
Also changed output buffer in pcAttackNpcs() from dynamically to
statically allocated. This in itself is temporary as I have a better
idea as to how we can allocate buffers with a bit less boilerplate.
