Add a new vernacular command for controling implicit generalization of
variables with syntax:
[Local?|Global] Generalizable Variable(s)? [all|none|id1 idn].
By default no variable is generalizable, so this patch breaks backward
compatibility with files that used implicit generalization (through
Instance declarations for example). To get back the old behavior, one
just needs to use [Global Generalizable Variables all].
Make coq_makefile more robust using [mkdir -p].
