It never really made sense for this to be asynchronous; most sources
didn't even do any IO to determine the directory. The only exception was
the git source, which would actually *clone a repository* if one didn't
exist yet. This heavyweight behavior wasn't a good fit for what looks
like a lightweight method anyway.

Making this synchronous has a ripple effect of making a bunch of other
methods synchronous, too. Hooray for synchrony!

Now instead of just saying how many packages failed to be
reinstalled/reactivated, "pub cache repair" will print a list of those
packages.

This also fixes an issue where "pub cache repair" would incorrectly
return a 0 exit code when packages failed to reactivate.

Closes #1301

A package's executables may not use all of that package's transformers. This is
especially true for browser frameworks where there's a clear divide between
client-side and server-side code. This uses pub's existing dependency-sniffing
infrastructure to figure out which transformers can be omitted.

This takes "pub run polymer:new_element --help" from 1.52s to 0.96s.
