Marking variables as const when they won't be modified after
initialization helps programmers trying to understand a codebase to
manage the cognative load.
This pull request uses a clang-tidy fixit (Hard to automate, since the
code needs to be temporarily compiled as C++ for it to work) to try to
mechanically apply the const keyword to code where the automated tool
can determine that the variable won't be modified.
I then follow this up with a manual improvement pass to
turnutils_uclient, where I address const correctness of local variables,
as well as do some adjustments to loops and scoping to help with
reducing complexity.

With notable exceptions of:
src/apps/common/win/*
src/apps/relay/telnet.*
The purpose of this change is to add the SPDX tags from
https://spdx.dev/, which is a linux foundation project, to the source
code.
This provides automated code provenance tools, which are used in setting
up software bill of materials reports, an easy time verifying that the
code license is known and no incompatibilities are present in a
codebase.
No copyright date, author, or license changes are made.
Note also that
7e525c8e1c
is the original commit for the ACME code (acme.h and acme.c) which was
then moved to acme.h and acme.c in this commit
d4686750ee
but neither commit indicates what license the ACME code was submitted
as.
https://github.com/coturn/coturn?tab=License-1-ov-file#readme is the
3-clause BSD license, but https://github.com/coturn/coturn/pull/672
documents that the author's intent was for the MIT license. So I've used
the SPDX tag and content of the MIT license for this change.
Use the include-what-you-use program to (partially) clean up header
includes, so that only includes which are needed, and no includes that
are not needed (or at least closer to that ideal) are done.
For a c-language project, the build-time improvements from this change
is minimal. This would have a much bigger impact on a C++ project than a
C-project for build times.
So for coturn, this change is mostly intended to just provide
consistency and make it easier to locate weird issues like strange
dependencies, and unnecessary connections between code.
- Why? Because code where conditionals lack braces is much harder to read, and prone to indentation confusion.
- How? Just added an extra flag to .clang-format and re-ran clang-format on all the files.
I also moved .clang-format up to the top level of the repo so that it can be applied to the fuzz targets as well.
I would like to get feedback on this and see if people is confortable
with these clang rules.
Right now is using the "llvm" style increasing the line length from 80
to 120 given that coturn is using long lines often.

The following changes have been made:
1. Replace deprecated functions with new standard functions
2. Add corresponding MSVC functions for non-standard functions
3. Remove warnings about unsafe functions
4. CMAKE: modify find pack Libevent and openssl
5. Modify include files
6. Use pthread4W
7. Modify socket in windows
8. Add CI - github action
8.1. msvc
8.2. mingw
10. The database:
9.1. sqlite, pgsql, hiredis, mongo is test compiled.
9.2. mysql, isnot test compiled.
11. The applications、server can be compiled and run successfully!
12. Add vcpkg manifest mode in cmake.
Replace all instances of `bzero` with memset by find-replace-edit.
This is straightforward replacement which is suboptimal in a few cases
(for example we could use calloc instead of malloc+memset(0))
