tests: add more TCs for pool

and extend comments in existing ones.

Make exception_with_errormsg take arbitrary num of params

Fixes problem with loosing category on with_pmemobj_errormsg() call.

Fix file description and include guard name

to minimize dependencies of common.hpp

Add decoration to exceptions instead of calling method

Idea behind this PR is to remove duplicated methods from exception classes.

Make index_sequence helpers compatible with std versions

This change enables creating index_sequences from single number.

Disable useless graphs

Make cpp-format targets always working

Those graphs only add unnecessary complexity to the documentation.

As cpp-format targets are always generated anyway, they should work even
if CHECK_CPP_STYLE flag is disabled.

[string_view] add description for methods in string_view

Update doxygen config

Added missing description for methods and comment fix.

It generates a lot not relevant documentation for helper methods

It's needed to rename "Modules" section into "Features"

https://www.doxygen.nl/manual/customize.html

It's needed for ebr_0_drd and radix_concurrent_ierate_0_drd

Fixes #1076

Include graph is extremely unreadable, and not really useful

using Doxygen 1.9.1 version.

it has doxygen in version 1.9.x, which produces better documentation.
Also, removed additional 'hub --version' step in the auto-doc-update script,
since it appears to be redundant.

Fixes: #1010

Add copyright-format target to CMakeLists

disable 'maybe-uninitialized' compiler flag

in tests, examples and benchmarks - it produces many false-positives.
