Also remove some unused parameters/functions

Added the following chat coreside features
* Chat messages length limit
* Message rate limiting
* Message rate kicking

Note:
* handleChat now takes RemotePlayer pointer instead of u16 to remove useless
  lookups

Writing an u8 to verbosestream writes a char, not it's numeric value.

* No function overloading
* Adhere coding style and with method names following
  lowercase_underscore_style
* Use std::string in external API, handling these is
  much more fun

Fix regression of commit

5e507c98 "Add server side ncurses terminal"

which allowed all players, even those without a shout priv, to chat.

Fixes #3362.

This adds a chat console the server owner can use for administration
or to talk with players.
It runs in its own thread, which makes the user interface immune to
the server's lag, behaving just like a client, except timeout.
As it uses the same console code as the f10 console, things like nick
completion or a scroll buffer basically come for free.
The terminal itself is written in a general way so that adding a
client version later on is just about implementing an interface.

Fatal errors are printed after the console exists and the ncurses
terminal buffer gets cleaned up with endwin(), so that the error still
remains visible.

The server owner can chose their username their entered text will
have in chat and where players can send PMs to.
Once the username is secured with a password to prevent anybody to
take over the server, the owner can execute admin tasks over the
console.

This change includes a contribution by @kahrl who has improved ncurses
library detection.

Remove DTIME macro and its uses, too

- SRP: print the address only once, not twice
- Legacy: previously the address was not printed at all
- Make both messages structurally the same, to facilitate log analyzers

1. Do two renames:
	* SER_FMT_CLIENT_VER_LOWEST -> SER_FMT_VER_LOWEST_WRITE
	* SER_FMT_VER_LOWEST -> SER_FMT_VER_LOWEST_READ
Now the two define values are consistently named with the _WRITE defines
SER_FMT_VER_{HIGHEST,LOWEST}_WRITE, and to better point out what the two
serialisation versions actually are for.

2. wrap some lines in doc/worldformat.txt, and point out that the node
timers are serialized at a later point, as this can cause confusion about
what now happens (if one doesn't strictly read the if block's conditions).

3. some whitespace fixes in NodeTimerList::serialize, and one new comment.

-> Fix server crash with protocol >=25 if a default password is set.
-> Remove some useless and possibly confusion causing code for the TOCLIENT_FIRST_SRP packet handler

Use wide_to_utf8 and utf8_to_wide instead of wide_to_narrow and narrow_to_wide at almost all places.
Only exceptions: test functions for narrow conversion, and chat, which is done in a separate commit.

Thanks to @UltimateNate for pointing this out :)

Also, clean up surrounding code style
Replace by-value parameter passing with const refs when possible
Fix post-increment of iterators

Its a possible mistake to log in to a server with twice the same name.
Before, it triggered a server wide error message, now it logs to actionstream.

Also rename method to better match what it does.

This enables srp.

Adds everything needed for SRP (and everything works too),
but still deactivated, as protocol v25 init packets aren't final yet.
Can be activated by changing the LATEST_PROTOCOL_VERSION header to 25
inside networkprotocol.h.

Also fix std::logic_error when server::DenyAccess() is used with only two arguments.

Change types for passed password from wstring to string, which removes converting
back and forth in most cases. Move the narrow_to_wide conversion, where its neccessary,
closer to irrlicht. Remove trailing spaces in guiPasswordChange.cpp. Make parameters for
translatePassword passed as const reference.

This seems to be a debug message which has been forgotten to be removed.

Move debug streams to log.cpp|h

Move GUI-related globals to clientlauncher

Move g_settings and g_settings_path to settings.cpp|h

Move g_menuclouds to clouds.cpp|h

Move g_profiler to profiler.cpp|h

  * Combine client and server man pages.
  * Update unit test options and available databases in man page.
  * Add `--worldname` to man page.
  * Fix a bunch of places where `"Minetest"` was used directly instead of `PROJECT_NAME`.
  * Disable server build by default on all operating systems.
  * Make `ENABLE_FREETYPE` not fail if FreeType isn't found.
  * Enable LevelDB, Redis, and FreeType detection by default.
  * Remove the `VERSION_PATCH_ORIG` hack.
  * Add option to search for and use system JSONCPP.
  * Remove broken LuaJIT version detection.
  * Rename `DISABLE_LUAJIT` to `ENABLE_LUAJIT`.
  * Rename `minetest_*` variables in `version.{h,cpp}` to `g_*`.
  * Clean up style of CMake files.

Don't send an InventoryAction at each setInventoryModified, we only need one SendInventory per inventory modification

Client doesn't like to receive multiples SendInventory for one action, this can trigger glitches on clients (sometimes due to incorrect UDP packet ordering due to UDP protocol)

This fix issue #2544

This call was missing when change looping to triggering SendInventory: 1b2f6447

Use the NetworkPacket api to read full version string instead of u8 pointers. Also store the reserved byte to use API properly

Fixes #2509

* Requested by @Zeno-
* Approved by @nerzhul

* Mods can do setHP function to do damages and override the enable_damage value sometimes

* TOSERVER_INIT and TOCLIENT_INIT renamed to _LEGACY
* TOSERVER_PASSWORD merged from dev-0.5, can use protocol v24 and v25
* TOCLIENT_ACCESS_DENIED merged from dev-0.5, can use protocol v24 and v25, with normalized strings an a custom id for custom errors
* new TOSERVER_INIT packet only send MT version, supported compressions, protocols and serialization, this permit to rework everything later without break the _INIT packet
* new TOSERVER_AUTH packet which auth the client
* new TOCLIENT_HELLO packet which send server serialization version atm
* new TOCLIENT_AUTH_ACCEPTED which is send when TOCLIENT_AUTH was okay. After this packet, the client load datas from servers, like after TOCLIENT_INIT_LEGACY packet

Rename some packet and handlers to <packet>_Legacy name for compat layer between new network changes and old network clients

Add Player::isDead function to check player is dead
