Boost.Random imposes excessive compiler requirements that prevents
Boost.Log from being built and tested with 32-bit gcc 8 on MinGW-w64.
We only need a fast RNG to quickly shuffle sinks in case of thread
contention in the core.
Use a local implementation of xorshift64 for such an RNG, which should
be even faster than taus88 and have sufficiently good quality. Also,
use std::random_device to initialize the PRNG. Keep the clock/thread_id
based initialization as a backup, in case if std::random_device fails.

This lets users to disable Boost.ASIO-related functionality and remove
the dependency on Boost.ASIO. This may be useful on platforms where
Boost.ASIO or its dependencies don't work or disabled.

* Make the library modular usable.
* Switch to library requirements instead of source. As source puts extra source in install targets.
* Clean up build dependencies.
* Remove external build references and avoid custom project loading.
* Use relative paths to declare config sub-projects.
* Add missing NO_LIB usage requirements.
* Add missing library ref.
* Add missing import-search for cconfig/predef checks.
* Add requires-b2 check to top-level build file.
* Update dependencies.
* Bump B2 require to 5.2
* Update copyright dates.
* Move inter-lib dependencies to a project variable and into the build targets.
* Remove custom symbolic project names for config subprojects. And use project root relative targets.
* Move private deps to the build project.
* Put back default boost locale link as locale build is now fixed.
* Set default address-model and architecture to avoid extra/custom detection logic. Put back missing check and config rules.
* Adjust doc build to avoid boost-root references.
* Fix ref to predef.jam location.
* Have B2 build use same deps as CML for per-target private/public.
* Add log dep to log_setup, as it's needed on some platforms.
* Add boost_log_with_support target to mirror CML.
* Fix platform specific winapi dependency spec.
This replaces boost::thread and most mutexes and condition variables with
std equivalents. It also adds support for std lock types to the strictest_lock
type trait.
This significantly, although not completely, reduces the dependency on
Boost.Thread.

Boost.Log supports compilers that do not qualify as C++11 compilers
for Boost.Regex, even if they are compiling in C++11 mode. In that
case, we still need to link with Boost.Regex v4 prebuilt library.
For more recent compilers, Boost.Regex v5 is used, and that is
a header-only library. This commit removes linking with Boost.Regex
when this is detected at configure time.
Note that only Boost.Build is updated. CMake doesn't need to be
updated since even header-only libraries need to be listed as
dependencies.
Closes https://github.com/boostorg/log/pull/219.
This is to work around target Windows version mismatch between Boost.Log
and test/examples code caused by other libraries (e.g. Boost.SmartPtr)
including windows.h without using Boost.WinAPI or defining the target
Windows version. Windows SDK defines its own default target version,
which doesn't necessarilly match the default in Boost.WinAPI, which
is used when building Boost.Log.
By not using windows.h when building tests and examples we make the
other libraries to provide their own definitions of WinAPI components
instead of including windows.h, and therefore avoid them defining a
different target Windows version.
The _SCL_SECURE_NO_WARNINGS, _SCL_SECURE_NO_DEPRECATE,
_CRT_SECURE_NO_WARNINGS and _CRT_SECURE_NO_DEPRECATE macros need to be
defined for every compiler that uses MSVC C/C++ runtime, so instead of
duplicating these definitions in multiple places, define them for
Windows platform regardless of the compiler. In particular, they are
now defined for clang-cl.
The implementation in Boost.Core was based in unhandled_exception_count
in Boost.Log, therefore we remove our loca implementation in favor
of the common one.
Boost.Build offers better compatibility with different compilers, some of
which use different flags for changing the default visibility. This also
slightly simplifies Boost.Log Jamfile.
The auto-detection was removed in 1.62, which resulted in UDP socket-based implementation being always used. The new auto-detection verifies the presence of syslog.h and all required components it provides.
Fixes ticket #12600.
Include winapi/config.hpp as soon as possible; avoid including even
Boost.Config before it so that it doesn't set Windows API version
accidentally by including some third party header. In all source files,
include detail/config.hpp or detail/setup_config.hpp first thing.
Moved all WinAPI config macros to the Jamfile.v2 and removed
windows_version.hpp as it was no longer needed. Also enabled inclusion of
windows.h while compiling the library.
Removed auto-linking with psapi.lib and advapi32.lib as it was no longer
working after ecf3114. Added linking with advapi32.lib to Jamfile.v2.
