Fix 01603d9e: [Preview] publishing preview failed due to recent changes (#9621)

Since 01603d9e we run under root, not under github user. In result,
the location of "aws" binary changed.

Fix 3046a6ce: [Preview] building preview failed to patch LZMA (#9620)

The job was started under a non-priv user, which did not have
permission to patch the emscripten files required to make LZMA
work.

Codechange: "set but not used" warning when disabling assert() (#9613)

DebugCheckSanity() is unused when asserts are disabled. While at it,
use WITH_ASSERT over NDEBUG, as that means we also run this code
during beta/RC.

Add: [Network] Keep the refresh button in lowered state while refreshing (#9600)

This gives user visual feedback that the refresh is still pending, and
prevents people from clicking again and again thinking nothing is
happening. This is especially true for connections that fall back to
TURN, as that takes a few seconds to kick in.

Additionally, prevent clicking on the button again while a refresh
is pending. This is only delaying a successful result.

Fix #9588, 140a96b: [Squirrel] Reaching memory limit during script registration could prevent further script detections (#9589)

Also the memory allocation triggering the limit was never freed.
And if the exception was thrown in a constructor using placement new, the pre-allocated memory was not freed either.

Add: use of Intel Intrinsics & RDTSC on e2k (MCST Elbrus 2000) (#9575)

MCST e2k (Elbrus 2000) architecture has half native / half software support of most Intel/AMD SIMD
e.g. MMX/SSE/SSE2/SSE3/SSSE3/SSE4.1/SSE4.2/AES/AVX/AVX2 & 3DNow!/SSE4a/XOP/FMA4

E2K - this is VLIW/EPIC architecture, like Intel Itanium (IA-64) architecture.

Fix: Incorrect error messages on placing water on scenario editor (#9560)

Additionally changes the behaviour of placing sea on sea/river/canal and placing canal/river on canal to (over)build, instead of disallowing it

Add: [Network] On join, log the ClientID + IP + Name clearly (#9558)

Additionally, reword the disconnect to match connect / join messages.

Fix: Prevent train reversing when wholly inside a train depot (#9557)

Fix: wrong error message when building canals over ship depots / locks

IsTileType() also considers ship depots and locks water. IsWaterTile() does the right thing.

Fix: reduce cost of building canals over objects on sea

It is not like we will drain the sea first, to put water back in it after.
Besides, the cost for draining the sea isn't calculated for all other cases either.

Doc: update multiplayer documentation with latest changes (#9552)

Although several places were fixed during the PR making the change,
not all made it in this document.

While at it, removed all kinds of Markdown warnings by an excessive
usage of spacebar in this document.
