d47dd94162 eal/windows: do not install virt2phys header
The header was not intended to be a public one.
DPDK users should use `rte_mem_virt2iova()` to translate addresses.
Other virt2phys users should use the header from the driver instead.

694c81721e eal/windows: fix CPU cores counting
On Windows, -l/--lcores EAL option was unable to process CPU sets
containing CPUs other than 0 and 1, because CPU_COUNT() macro
only checked these CPUs in the set. Fix CPU_COUNT() by enumerating
all possible CPU indices.

f1f6ebc0ea eal: remove sys/queue.h from public headers
Currently there are some public headers that include 'sys/queue.h', which
is not POSIX, but usually provided by the Linux/BSD system library.
(Not in POSIX.1, POSIX.1-2001, or POSIX.1-2008. Present on the BSDs.)
The file is missing on Windows. During the Windows build, DPDK uses a
bundled copy, so building a DPDK library works fine.  But when OVS or other
applications use DPDK as a library, because some DPDK public headers
include 'sys/queue.h', on Windows, it triggers an error due to no such
file.

One solution is to install the 'lib/eal/windows/include/sys/queue.h' into
Windows environment, such as [1]. However, this means DPDK exports the
functionalities of 'sys/queue.h' into the environment, which might cause
symbols, macros, headers clashing with other applications.

The patch fixes it by removing the "#include <sys/queue.h>" from
DPDK public headers, so programs including DPDK headers don't depend
on the system to provide 'sys/queue.h'. When these public headers use
macros such as TAILQ_xxx, we replace it by the ones with RTE_ prefix.
For Windows, we copy the definitions from <sys/queue.h> to rte_os.h
in Windows EAL. Note that these RTE_ macros are compatible with
<sys/queue.h>, both at the level of API (to use with <sys/queue.h>
macros in C files) and ABI (to avoid breaking it).

Additionally, the TAILQ_FOREACH_SAFE is not part of <sys/queue.h>,
the patch replaces it with RTE_TAILQ_FOREACH_SAFE.

warning appear:

warning: token pasting of ',' and __VA_ARGS__ is a GNU extension

5ffa86a2b4 build: propagate Windows system dependencies to pkg-config
Windows EAL depends on some system libraries. They were linked using
add_project_link_arguments('-l<LIB>'), which prevented meson from adding
them to Libs.private of pkg-config file. As a result, applications using
pkg-config to find DPDK hit link errors, for example:

    librte_eal.a(eal_windows_eal_debug.c.obj) : error LNK2019: unresolved
    external symbol __imp_SymInitialize referenced in function
    rte_dump_stack

Reference required libraries in EAL using ext_deps meson variable.
bus/pci and net/pcap depend on lib/eal and will pull them automatically.
Drop advapi32 dependency, as MinGW locates VirtualAlloc2() dynamically.

40edb9c0d3 eal: handle compressed firmware
Introduce an internal firmware loading helper to remove code duplication
in our drivers and handle xz compressed firmware by calling libarchive.

This helper tries to look for .xz suffixes so that drivers are not aware
the firmware has been compressed.

libarchive is set as an optional dependency: without libarchive, a
runtime warning is emitted so that users know there is a compressed
firmware.

Windows implementation is left as an empty stub.

cfdaa678b3 eal/windows: cleanup interrupt resources
Interrupt manager in Windows EAL allocates on IOCP and starts
a control thread that runs indefinitely. At DPDK cleanup
this thread was not stopped and IOCP handle was not closed.

Gracefully stop interrupt-handling in rte_eal_cleanup().
The thread already closes IOCP handle before exiting.

3888f31950 eal/windows: fix interrupt thread handle leakage
Each time a work was scheduled in the interrupt thread,
usually an alarm, a handle was opened but not closed.

Opening a handle is a system call, which harms alarm precision.
Instead of opening and closing a handle each time, open it
when interrupt thread starts and close it when the thread finishes.

8eff201b00 net/ice: fix leak on thread termination
A terminated pthread should be joined or detached so that its associated
resources are released.

The "ice-reset-<vf_id>" threads are used to service some reset task in
the background, but they are never joined by the thread that created
them.
The easiest solution is to detach new threads.

The Windows EAL did not provide a pthread_detach wrapper but there is no
resource to release for Windows threads, so add an empty wrapper.

99a2dd955f lib: remove librte_ prefix from directory names
There is no reason for the DPDK libraries to all have 'librte_' prefix on
the directory names. This prefix makes the directory names longer and also
makes it awkward to add features referring to individual libraries in the
build - should the lib names be specified with or without the prefix.
Therefore, we can just remove the library prefix and use the library's
unique name as the directory name, i.e. 'eal' rather than 'librte_eal'
