goinstall: select the tag that is closest to runtime.Version
release.r50 looks for newest tag <= go.r50 weekly.2010-10-10 looks for newest tag <= go.2010-10-10 Implements behavior for hg, git, and bzr. R=dsymonds, rsc, n13m3y3r CC=golang-dev https://golang.org/cl/4873057

causing goinstall to update all remote packages encountered during

the installation.

|

When downloading or updating, goinstall first looks for a tag or branch
|

named "release". If there is one, it uses that version of the code.
|
||||
When downloading or updating, goinstall looks for a tag with the "go." prefix
|
||||
that corresponds to the local Go version. For Go "release.r58" it looks for a
|
||||
tag named "go.r58". For "weekly.2011-06-03" it looks for "go.weekly.2011-06-03".
|

If the specific "go.X" tag is not found, it chooses the closest earlier version.
|
||||
If an appropriate tag is found, goinstall uses that version of the code.
|

Otherwise it uses the default version selected by the version control

system, typically HEAD for git, tip for Mercurial.
