[dpdk-dev] [PATCH v3 0/7] MinGW-w64 support

[Dmitry Kozlyuk <dmitry.kozliuk@gmail.com>]

This patch series add support for building DPDK using MinGW-w64.

MinGW-w64 provides GNU toolchain and independent platform SDK on
Windows. It also supports cross-compilation to Windows from POSIX
systems by providing cross tollchains and libraries [0]. It does NOT
emulate a full POSIX environment, like Cygwin or MSYS do.

There are advantages in using MinGW-w64 in addition to Clang:

1. Cross-compilation out-of-the-box. MinGW-w64 is provides a pthread
   implementation, GNU getopt, and Windows platform SDK.

2. Easier porting of POSIX applications using DPDK to Windows, because
   application code can use the same benefits as mentioned above.

3. Having both primary compilers enabled on Windows provides more
   diagnostics and generally prevents non-portable code.

v3 Changes:

    Rebase onto the latest Windows EAL.
    Prevent format attribute conflict with upcoming v20.05 patches.
    Remove redundant CFLAGS from Meson.
    Remove links to Meson bugtracker from docs (PR merged into upstream).
    Fix Clang warnings using about GNU options.

v2 Changes:

    Add patch to use lowercase system header filenames.
    Move Meson cross-file for x86 to arch directory.
    Change wording in comments.
    Add Meson version warning in documentation.
