[U-Boot] [PATCH v2 0/8] tools: Support building U-Boot host tools for Windows via MSYS2

[Bin Meng <bmeng.cn@gmail.com>]

Per current U-Boot README, building Windows versions of the utilities
in the tools directory is done via the MinGW toolchain. But testing
shows that it is broken and actually it must have been broken for
quite a long time.

Fixing MinGW build seems quite amount of work as developers of
U-Boot normally work on Linux boxes hence codes written are mainly
for Linux or POSIX OSes. We must investigate another way of building
host tools for Windows, and now we have MSYS2, a software distro and
building platform for Windows, to build POSIX compliant software on
Windows using an emulation layer.

This small series fixes several issues in current U-Boot tools codes,
that only assume a Linux host is used. Cases are using standard C
typedefs whenever possbile, or using compiler builtin functions to
improve portability, etc.

A reST document for how to build U-Boot host tools for both platforms
is added.

A new CI pipeline configuration for Microsoft Azure Pipelines is added
for U-Boot. We rely on it to ensure future host tools for Windows build
does not break. I've also investigated putting what we have for now on
GitLab-CI and Travis-CI to Azure Pipelines, but buildman hangs forever
and the root cause is not figured out yet.

Changes in v2:
- new patch: Add .gitattributes for line endings
- new patch: tools: Avoid creating symbolic links for tools/version.h
- new patch: Add Micirosoft Azure pipelines configuration
