[v4,0/6] Enable the internal EAL thread API

From: Narcisa Vasile <navasile@microsoft.com>

This patchset enables the new EAL thread API.
The newly defined thread attributes, priority and affinity,
are used in eal/windows when creating the threads. Similarly, 
some changes have been done in eal/linux/eal.c and eal/freebsd/eal.c
to initialize priority to a default value and set thread attributes.

The user is offered the option of either using the rte_thread_* API or
a 3rd party thread library, through a meson flag
called "use_external_thread_lib".
By default, this flag is set to FALSE, which means Windows libraries
and applications will use the EAL rte_thread_* API 
defined in windows/rte_thread.c for managing threads.
When the flag is set to TRUE, the common/rte_thread.c file is compiled
and an external thread library is used.

This patchset adds a new function for creating control threads that
uses the new thread API.
It enables the usage of the new function in Windows code and common code.
The old function is kept to avoid ABI break, however, its definition
is commented away on Windows, since the pthread_t and pthread_attr_t
arguments that it receives have been replaced with the new API on Windows.
This allows testing the "eal: Add EAL API for threading" that this
patchset depends on.

The ethdev lib also contains some changes that break the ABI.
Enabling the new EAL thread API will probably require going through
the proper process of ABI changes.

Depends-on: series-18172 ("eal: Add EAL API for threading")

v4:
- Free resources on error path
- Use RTE_FINI to unload kernel32.dll

v3:
- use RTE_INIT to only load kernel32.dll once and get function
  pointer to SetThreadDescription()
- minor fixes

v2:
- fix typo in SetThreadDescription_type function pointer
- add Depends-on on all patches to fix apply errors.
- modify cover letter

Narcisa Vasile (6):
  eal: add function that sets thread name
  eal: add function for control thread creation
  Enable the new EAL thread API in app, drivers and examples
  lib: enable the new EAL thread API
  eal: set affinity and priority attributes
  Allow choice between internal EAL thread API and external lib
