py3: handle keyword arguments correctly in hgext/largefiles/

Keys of keyword arguments must be str(unicode) on Python 3. The transformer
which we use on Python 3, appends b'' in front of each string literal, so this
may lead in KeyError or None return even when the key is present by we are using
bytes value and it's stored in unicodes. This patch and all the similar patches
handle this by either converting the keys of kwargs to bytes using
'pycompat.byteskwargs()' or adding r'' so that the transformer won't append
b''.

This next 23 patches follows the above mentioned way to handle keyword
arguments.

# Extract version number into 4 parts, some of which may be empty:
#
# version: the numeric part of the most recent tag. Will always look like 1.3.
#
# type: if an rc build, "rc", otherwise empty
#
# distance: the distance from the nearest tag, or empty if built from a tag
#
# node: the node|short hg was built from, or empty if built from a tag
