1) create go-tool dir in make.bash
2) clean up stale binaries in make.bash
3) add 'tool' command to go
4) convert goyacc->yacc as a first test tool
Since goyacc stands alone, it's a safe trial.

Added flag AllMethods: if not set (future default), embedded
methods of exported (and thus visible) embedded fields are not
shown in the final package documentation

The actual change for AllMethods is just in sortedFuncs. All
other changes are simplifications of the existing logic (mostly
deletion of code): Because method conflicts due to embedding
must always be detected, remove any premature elimination of
types and methods. Instead collect all named types and all
methods and do the filtering at the end.

Miscellaneous:
- renamed baseType -> namedType
- streamline logic for recording embedded types
- record embedded types via a map (simpler data structures)

AllMethods is set by default; so the output is unchanged and
the tests pass. The next CL will enable the AllMethods flag
and have adjusted tests (and fix issue 2791).

The use of gccgo is triggered by GC=gccgo in environment. It

This solves the ambiguity for "lp.net/project/foo". In these URLs,
"foo" could be a series name registered in Launchpad with its own
branch, and it could also be the name of a directory within the
main project branch one level up.

Solve it by testing if the series branch exists in Launchpad
and if it doesn't moving the root one level up.

The new url.URL's parsing can be too canonicalizing for

around, we give applications a gross escape hatch while

Especially for packages with large APIs, this makes the
overview more promiment, so that it can give the appropriate
context for reading the API list.  This should help significantly
in packages with large APIs, like net, so that the first thing users
see is not a jumble of functions but an introduction to the package.
