url: new package
...
This is just moving the URL code from package http into its own package,
which has been planned for a while.
Besides clarity, this also breaks a nascent dependency cycle the new template
package was about to introduce.
Add a gofix module, url, and use it to generate changes outside http and url.
Sadness about the churn, gladness about some of the naming improvements.

cgo: omit duplicate symbols in writeDefs
...
When the C API being used includes multiple names for the same
underlying symbol (e.g. multiple #define's for the same variable), then
cgo will generate the same placeholder variables for each name. This
then prevents the code from compiling due to multiple declarations of
the same variable - so change cgo to only create one instance of the
variable for the underlying symbol.

runtime: improve Linux mutex
...
The implementation is hybrid active/passive spin/blocking mutex.
The design minimizes amount of context switches and futex calls.
The idea is that all critical sections in runtime are intentially
small, so pure blocking mutex behaves badly causing
a lot of context switches, thread parking/unparking and kernel calls.
Note that some synthetic benchmarks become somewhat slower,
that's due to increased contention on other data structures,
it should not affect programs that do any real work.
