go.tools/go/gccgoimporter: keep track of package and import priority
...
Clients such as compilers need this information in order
to correctly link against imported packages.
This also adds support for the condensed import data format
where the priority information is stored as a suffix of the
condensed import data, as well as support for archive files.

go.tools/go/importer: fine-tuning of export format, test against std lib
...
(TBR adonovan)
- provide version string rather than version number (more flexible)
- match naming of tag constants with documentation (forth-coming)
- more formats for constant values (1-byte booleans, short 64bit
values, support for floating point numbers +123p+45)
- more regular format for signatures: always print with type tag;
this permits (future) sharing of identical signatures and possibly
large export data size reduction
- test export and import of all type-checked std library packages
- compare import of all std library packages against corresponding
import of gc-generated export data and verify that the packages
match 100% (except for floating point values which are exact when
coming from go/types, and possibly inexact when coming from gc)
On average, export data generated by the importer is ~28% of the size
of the gc-generated export data for corresponding packages of the std
library:

go.tools/go/importer: simplified exporter/importer
...
By using a simple (graph-based) serialization algorithm
and binary encoding, a significantly more compact export
data format is achieved than what the current compilers
use. Furthermore, the exporter and importer are completely
symmetric algorithms that are compact, and much easier to
change/expand.
