3535: Fix a possible race in load code r=def- a=heinrich5991
Previously, a save could possibly be loaded twice given enough latency
discrepancy between servers. The server only verified that it deleted
*some* save with the given password, not *the* save it is trying to
load. This is fixed by also checking the SaveID column that is random
and globally unique (except for the old NULLs). Since users can't create
new saves with NULL SaveID, these pose no problem.
Also change the default UUID for saves without save ID to something
nonzero, so we can't accidentally hit it due to a bug.

2742: Add str_utf8_copy that trim broken utf8 sequence at the end. r=heinrich5991 a=TsFreddie
Currently this replaces `str_copy` text input and clipboard paste in chat. Many places may need the same treatments, like steam names.

2202: Send DDNet version early in the connection process r=Learath2 a=heinrich5991
This gets rid of the problem that we don't know whether we should send
full snapshots to clients because they haven't told us about them being
DDNet yet.

This came from a long discussion comparing PCG-* against xoroshiro*. Do
not generate integers without bias because it doesn't affect us very
much and it is easier to reimplement with modulo.
This gets rid of the problem that we don't know whether we should send
full snapshots to clients because they haven't told us about them being
DDNet yet.

There were color functions everywhere, I tried cleaning it up a little. I still couldn't get the roundtrip from Hsl to Rgb to be exactly the same, but I think this is the best possible.

Quoting the man page of vsnprintf:
RETURN VALUE
Upon successful return, these functions return the number of characters printed
(excluding the null byte used to end output to strings).
The functions snprintf() and vsnprintf() do not write more than size bytes (including
the terminating null byte ('\0')). If the output was truncated due to this limit,
then the return value is the number of characters (excluding the terminating null
byte) which would have been written to the final string if enough space had been
available. Thus, a return value of size or more means that the output was truncated.
(See also below under NOTES.)
If an output error is encountered, a negative value is returned.
[...]
The glibc implementation of the functions snprintf() and vsnprintf() conforms to the
C99 standard, that is, behaves as described above, since glibc version 2.1. Until
glibc 2.0.6, they would return -1 when the output was truncated.
