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.

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.

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).

godoc/httpzip.go: use correct path in Readdir
...
Fixes a problem where Readdir would always return
empty directories (Readdir is only called by godoc
if the usual directory handler is commented out
in godoc.go, and if a zip file system is provided;
thus, this bug never manifested itself in godoc).
Also:
- better choice of variable/field names

go/parser: report illegal label declarations at ':' rather than guessing the start
...
Also:
- Add parser.SpuriousError flag. If set, the parser reports all (including
spurious) errors rather then at most one error per line.
- Add -e flag to gofmt and gotype: If set, gofmt and gotype report all
(including spurious) errors rather than at most one error per line.
- Updated the respective documentation.
Fixes #2088 .

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 .
NOTE: Tested on Linux amd64/386/arm only.
