policy: relax the default for in-place build

We're going to make the 'c' policy more strict, where no missing attribute
will be allowed. Since we want to run 'hg bisect' without rebuilding the C
extension modules, we'll need a looser policy for development environment.

The default for system installation isn't changed.

Note that the current 'c' policy is practically 'allow'-ish as we have lots
of adhoc fallbacks to pure functions.

#    allow - allow pure Python implementation when C loading fails
#    cffi - required cffi versions (implemented within pure module)
#    cffi-allow - allow pure Python implementation if cffi version is missing
#    py - only load pure Python modules
#
# By default, require the C extensions for performance reasons.
policy = b'c'
policynoc = (b'cffi', b'cffi-allow', b'py')
policynocffi = (b'c', b'py')
