Summary:
The clang-format file in scm/hg basically only applies to things in the
scm/hg/mercurial directory.
There are 180 C and C++ files under scm/hg, and the vast majority of them do
not follow the style specified in this clang-format file. All but 11 of these
files were present in scm/hg/contrib/clang-format-blacklist.
Of the 11 files that do follow this style, 10 are in the scm/hg/mercurial/
directory. (10 of the 21 files in this directory use this style.) The 1
other file is in scm/hg/contrib/xdiff.
The majority of the C/C++ files in scm/hg/hgext/extlib and scm/hg/lib/ follow
a style closer to Facebook and Google's C++ style guidelines.
Therefore this moves the .clang-format file to scm/hg/mercurial, and lets the
main fbsource clang-format file apply to the other files under scm/hg

Editorconfig (http://editorconfig.org/) is a file format helping define coding
styles like spaces, tabs etc. It supports a wide range of editors. Some well-
known projects like ruby and zsh are using it already.
This patch adds a simple .editorconfig, making it clear we use 8-char tabs in
C code, 4-char spaces in Python code, and we don't keep trailing spaces.
