Recommend the latest known working version
and warn about the issue and the affected versions.

Windows GSG included a section only on virt2phys driver installation,
but not on NetUIO. The content of the section duplicated documentation
in dpdk-kmods, but contained no links to it, only a reference.
Add subsections for virt2phys and NetUIO, explaining their roles.
Refer to documenttion in dpdk-kmods as an authoritative source,
but leave specific diagnostic and usage hints in the GSG.

Meson with Windows clang generates incorrect linker flag
"--subsystem,console" instead of "/subsystem:console" which
will fail the DPDK build. This is discovered at porting testpmd.
Meson 0.57.0 has the fix and should be used for DPDK Windows build.
Update the WindowsGSG DPDK Build document for the proper meson version.

Bump Meson required version to 0.49.2 which is chosen so as
to be provided by both redhat-8 and debian-10.
Update documentation and travis setup script accordingly.
This fixes the following warning:
WARNING: Project targeting '>= 0.47.1' but tried to use feature introduced
in '0.48.0': console arg in custom_target
'console' argument is used within kernel/linux/kni/meson.build

The Meson cross file is renamed from meson_mingw.txt to cross-mingw,
and is added to test-meson-builds.sh.
The only example supported on Windows so far is "helloworld",
that's why the default list of examples is overridden.

Provide a more direct link for installer download and clarify thread
model choice during installation. As pthread is not a requirement,
remove notice about its possible runtime dependency.

Basic memory management supports core libraries and PMDs operating in
IOVA as PA mode. It uses a kernel-mode driver, virt2phys, to obtain
IOVAs of hugepages allocated from user-mode. Multi-process mode is not
implemented and is forcefully disabled at startup. Assign myself as a
maintainer for Windows file and memory management implementation.

Add hugepages discovery ("large pages" in Windows terminology)
and update documentation for required privilege setup. Only 2MB
hugepages are supported and their number is estimated roughly
due to the lack or unstable status of suitable OS APIs.
Assign myself as maintainer for the implementation file.

With memory management implemented for Windows, the guide for running
sample applications is going to be extended with hugepages and driver
setup. Move run instructions to a separate file to give space for
planned expansion.

Add Meson configuration to cross-compile for Windows using MinGW-w64.
It may require adjustments in some cases, but at least it provides
the foundation.

MinGW-w64 linker does not mimic MS linker options, so the build system
must differentiate between linkers on Windows. Use GNU linker options
with GCC and MS linker options with Clang.
MinGW-w64 by default uses MSVCRT stdio, which does not comply to ANSI,
most notably its formatting and string handling functions. MinGW-w64
support for the Universal CRT (UCRT) is ongoing, but the toolchain
provides its own standard-complying implementation of stdio. The latter
is used in the patch to support formatting in DPDK.

The option -Dexamples=helloworld is missing.
The helloworld binary name was wrong.
Forcing clang may be required in some environments.
