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

Cleanup: remove str_strip_colours; StrMakeValid also removes the colours

Essentially str_strip_colours followed by StrMakeValid makes the calling of
str_strip_colours useless, as StrMakeValid would have removed them too.

Codechange: replace IConsolePrintF with IConsolePrint and fmt formatting

Also make some strings more consistent with the rest of the console strings.

Cleanup: remove IConsoleWarning/IConsoleError helpers

Both did not support format parameters, so in many places IConsolePrint(CC_ERROR, "message") was used with a style different from what IConsoleError would do.

Change: unify the style of console error messages and convert to fmt

Always start with a capital, do not add "ERROR: " in front of it.

Codechange: rename str_validate to StrMakeValid(InPlace) (#9304)

This to be more explicit the function changes the value, and not
returns yes/no.

Codechange: Use std::string in console commands/aliases registration, and std::map instead our sorted linked list (#9057)

* Codechange: Use std::string in console commands and aliases registration

* Codechange: Use std::map to register console commands

* Codechange: Use std::map to register console aliases

* Cleanup: Remove now unused function

Remove: ENABLE_NETWORK switch

This switch has been a pain for years. Often disabling broke
compilation, as no developer compiles OpenTTD without, neither do
any of our official binaries.

Additionaly, it has grown so hugely in our codebase, that it
clearly shows that the current solution was a poor one. 350+
instances of "#ifdef ENABLE_NETWORK" were in the code, of which
only ~30 in the networking code itself. The rest were all around
the code to do the right thing, from GUI to NewGRF.

A more proper solution would be to stub all the functions, and
make sure the rest of the code can simply assume network is
available. This was also partially done, and most variables were
correct if networking was disabled. Despite that, often the #ifdefs
were still used.

With the recent removal of DOS, there is also no platform anymore
which we support where networking isn't working out-of-the-box.

All in all, it is time to remove the ENABLE_NETWORK switch. No
replacement is planned, but if you feel we really need this option,
we welcome any Pull Request which implements this in a way that
doesn't crawl through the code like this diff shows we used to.

(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 r11579) -Revert(r11578): some cases of key propagation are not handled correctly.
A better solution will be deviced, but not now. Let's not cause a ton of bug reports

(svn r11578) -Codechange: Introduce the window default flag WDF_TEXTENTRY which specifies that the window holding it is actually one that enables an edit box.
Use this flag when dispatching a key event instead of using some hard coded window IDs.
This should ease a little bit the creation of new edit aware windows.
