Currently, we don't have package testing to import package regexp directly,
because then regexp can't have internal tests (or at least they become more
difficult to write), for fear of an import cycle. The solution we've been using
is for the generated test main package (pseudo-import path "testmain", package main)
to import regexp and pass in a matchString function for use by testing when
implementing the -run flags. This lets testing use regexp but without depending
on regexp and creating unnecessary cycles.
We want to add a few dependencies to runtime/pprof, notably regexp
but also compress/gzip, without causing those packages to have to work
hard to write internal tests.
Restructure the (dare I say it) dependency injection of regexp.MatchString
to be more general, and use it for the runtime/pprof functionality in addition
to the regexp functionality. The new package testing/internal/testdeps is
the root for the testing dependencies handled this way.
Code using testing.MainStart will have to change from passing in a matchString
implementation to passing in testdeps.TestDeps{}. Users of 'go test' don't do this,
but other build systems that have recreated 'go test' (for example, Blaze/Bazel)
may need to be updated. The new testdeps setup should make future updates
unnecessary, but even so we keep the comment about MainStart not being
subject to Go 1 compatibility.

Files in this directory are data for Go's API checker ("go tool api", in src/cmd/api).
Each file is a list of API features, one per line.
go1.txt (and similarly named files) are frozen once a version has been
shipped. Each file adds new lines but does not remove any.
except.txt lists features that may disappear without breaking true
compatibility.
next.txt is the only file intended to be mutated. It's a list of
features that may be added to the next version. It only affects
warning output from the go api tool.
