Rob Pike 1d8f822c17 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.

Julian Phillips 01dd57b312 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.

Dmitriy Vyukov 54e9406ffb runtime: add more specialized type algorithms 
The change adds specialized type algorithms
for slices and types of size 8/16/32/64/128.
It significantly accelerates chan and map operations
for most builtin types as well as user structs.

Dmitriy Vyukov 4e5086b993 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.

Andrew Gerrand fc2480da3c goinstall: write to goinstall.log in respective GOPATH 
goinstall: report every newly installed package to the dashboard

This makes "goinstall -a" work on systems with GOROOTs that are
not user-writable, as is the case with Debian's Go packages.

This also makes goinstall.log the canonical list of installed
packages, in that only packages new to goinstall.log are reported to
the dashboard.

A side-effect is that writing to goinstall.log is now mandatory.
(A bug in the original implementation meant this was the case, anyway.)

The principal benefit of this change is that multiple packages from the
same repository can now be reported to the dashboard.  It is also less
likely for a user to report multiple installations of the same package
to the dashboard (they would need to remove the package from
goinstall.log first).

thus, this bug never manifested itself in godoc).

Gustavo Niemeyer ba2e3af177 ld: remove overlap of ELF sections on dynamic binaries 
The dynamic ELF sections were pointing to the proper data,
but that data was already owned by the rodata and text sections.
Some ELF references explicitly prohibit multiple sections from
owning the same data, and strip behaves accordingly.

The data for these sections was moved out and their ranges are
now owned by their respective sections.  This change makes strip
happy both with and without -s being provided at link time.

A test was added in debug/elf to ensure there are no regressions
on this area in the future.

Fixes #1242.
Fixes #2022.

Robert Griesemer df68a61c9e godoc: support for file systems stored in .zip files 
Instead of serving files of the underlying OS file system,
a .zip file may be provided to godoc containing the files
to serve; for instance:

   godoc -http=:6060 -zip=go.zip

using a .zip file created from a clean tree as follows:

   zip -r go.zip $GOROOT

David Anderson f1df07bf6a 5l, 6l, 8l: Add a PT_LOAD PHDR entry for the PHDR. 
Per the TIS ELF spec, if a PHDR entry is present in the
program header table, it must be part of the memory image of
the program. Failure to do this makes elflint complain, and
causes some tools that manipulate ELF to crash.
