This correctly fixes issue #1362.
chpos/byte_pos are now the offsets within a particular file, but
rather the offsets within a virtual file with is formed by combing all
of the modules within a crate. Thus, resetting them to 0 causes an
overlap and hence, bogus source locations.
Fix#1362 by moving chpos/byte_pos to parse_sess so that
new_parser_from_source_str has access to them and hence can chose an
initial value that is not already been used in the crate.
Note that the trigger for bug 1361 was that syntax/ext/expand.rs calls
parse_expr_from_source_str (which calls new_parser_from_source_str)
using the same codemap as the current crate (and hence causing overlap
with files in the crate as new_parser_from_source_str resets the
chpos/byte_pos to 0).
Use ifaces instead of objs, stop wrapping everything in two (or three)
layers of no-value-added indirection, and remove some of the more
pointless/outdated idioms from the code.
In aid of search, add a new field to the packages.json format, called "tags",
whose value is a list of strings. Search accepts a list of tags, all of which
must match for the package to be shown.

Indexes are listed in ~/.cargo/sources.json and ~/.cargo/local-sources.json, the
former of which is stored in the rust source tree in src/cargo. Each entry in
either of these files is a source, which is a dictionary with (currently) a
single key, "url". The supplied url should point to a json list, each element of
which should be a dictionary with four keys: "name", "uuid", "url", and
"method". The name and uuid serve to identify the package; the method describes
how to fetch the package; the url describes where to fetch it from. Currently
supported methods are "git", "http", and "file".
