Change: forcefully enable prefixing logs with date (#11930)

Additionally, add the log-level to the log message.

Codechange: Replace C-style TICC/TOCC macros with C++ RAII implementation. (#11857)

Usage is more robust, and will always include timing when the TicToc object goes out of scope.

Remove: rdtsc and TIC/TOC based on CPU ticks (#11856)

Use TIC/TOC based on std::chrono instead. This information is also
easier to compare with others, as although it depends on CPU, it
means a bit more if "yours takes 4ms and mine takes 10ms".

Fix #11646: Non-thread safe shared buffer returned from GetLogPrefix().

Return string from GetLogPrefix instead of shared string's buffer.

Codechange: automatic adding of _t to (u)int types, and WChar to char32_t

for i in `find src -type f|grep -v 3rdparty/fmt|grep -v 3rdparty/catch2|grep -v 3rdparty/opengl|grep -v stdafx.h`; do sed 's/uint16& /uint16 \&/g;s/int8\([ >*),;[]\)/int8_t\1/g;s/int16\([ >*),;[]\)/int16_t\1/g;s/int32\([ >*),;[]\)/int32_t\1/g;s/int64\([ >*),;[]\)/int64_t\1/g;s/ uint32(/ uint32_t(/g;s/_uint8_t/_uint8/;s/Uint8_t/Uint8/;s/ft_int64_t/ft_int64/g;s/uint64$/uint64_t/;s/WChar/char32_t/g;s/char32_t char32_t/char32_t WChar/' -i $i; done

Codechange: fmt (and std::format) do explicitly not support enums out-of-the-box

That it works for the version we have packaged it pure coincidence, as that is
one of the few versions that due to a bug allow it. So add the appropriate
template specialisations to support it out-of-the-box within OpenTTD.

Change: Rename some freetype things to fontcache.

The font cache supports more than just FreeType as a font provider, but still used freetype in some naming.

This now uses more suitable terms.

Cleanup: changing variable names in TIC() and TOC()

Removing double underscores to be ANSI-C standard compliant.

Remove: NO_DEBUG_MESSAGES was only read and setting it broke compilation (#6703)

Given any speed issue cannot be attributed to checking for _debug_NNN_level, removing this is a safe action

This fixes #6652.

(svn r16269) -Codechange: use gcc's ability to check parameters sent to printf-like functions
-Fix: wrong number of parameters or wrong parameter types sent to printf-like functions at several places

(svn r8605) -Codechange: [OSX] changed all objective C to objective C++
This will permanently solve the issue where compilation on OSX broke because C++ code was added to some header files

-Note: (important if you develop mac specific code)
taken from http://developer.apple.com/releasenotes/Cocoa/Objective-C++.html
gdb lacks an integrated C++ with Objective-C parser. This means that gdb won't be able to evaluate expressions that contain both C++ and Objective-C constructs.
gdb assumes that the language for ".mm" files is C++.
you can change it to objective C by typing: (gdb) set language objc
Mixing C++ and objective C has some limitation (see link for all of them)

(svn r7759) -Merge: makefile rewrite. This merge features:
- A proper ./configure, so everything needs to be configured only once, not for every make.
- Usage of makedepend when available. This greatly reduces the time needed for generating the dependencies.
- A generator for all project files. There is a single file with sources, which is used to generate Makefiles and the project files for MSVC.
- Proper support for OSX universal binaries.
- Object files for non-MSVC compiles are also placed in separate directories, making is faster to switch between debug and release compiles and it does not touch the directory with the source files.
- Functionality to make a bundle of all needed files for for example a nightly or distribution of a binary with all needed GRFs and language files.

Note: as this merge moves almost all files, it is recommended to make a backup of your working copy before updating your working copy.
