exewrapper: convert to _tcsxxx functions for Unicode compatability

This fixes more than 50 tests on py3 on Windows when enabled, mostly hooks and
such that invoked `hg` directly.  187 left to go.

I skipped doing the abort printing with Unicode because of apparent issues with
MinGW [1].  It may be moot though, as MinGW isn't listed as a supported compiler
after 3.4 [2].
