py3: use pycompat.fsdecode() to pass to imp.* functions

When we try to pass a bytes argument to a function from imp library, it
returns TypeError as it deals with unicodes internally. So we can't use bytes
with imp.* functions. Hunting through this, I found we were returning bytes
path variable to loadpath() on Python 3.5 (yes most of our codebase is
dealing with bytes on Python 3 especially the path variables). Passing unicode
does not fails the purpose of loding the extensions and a module object is
returned.

from __future__ import absolute_import, print_function

import os
from hgext import (
    color,
)
from mercurial import (
    dispatch,
    ui as uimod,
)

# ensure errors aren't buffered
testui = color.colorui()
testui.pushbuffer()
testui.write(('buffered\n'))
testui.warn(('warning\n'))
testui.write_err('error\n')
print(repr(testui.popbuffer()))

# test dispatch.dispatch with the same ui object
hgrc = open(os.environ["HGRCPATH"], 'w')
hgrc.write('[extensions]\n')
hgrc.write('color=\n')
hgrc.close()

ui_ = uimod.ui.load()
ui_.setconfig('ui', 'formatted', 'True')

# we're not interested in the output, so write that to devnull
ui_.fout = open(os.devnull, 'w')

# call some arbitrary command just so we go through
# color's wrapped _runcommand twice.
def runcmd():
    dispatch.dispatch(dispatch.request(['version', '-q'], ui_))

runcmd()
print("colored? " + str(issubclass(ui_.__class__, color.colorui)))
runcmd()
print("colored? " + str(issubclass(ui_.__class__, color.colorui)))
