8fdc2851e4 zip: add a test for the previous >65k files fix
This surprisingly takes 30 seconds on my fast machine

a667e44e75 lib9: use $PWD in getwd
This makes the full file paths recorded by 6g
prefer $PWD over the actual directory name
(relevant when $PWD gets to the current directory
via symlinks).  It's what everyone else does, and
what people expect.

fa497796f5 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.

17d9093bf2 undo CL 4808044 / 1bd754e69ce7
ServeMux depends on having a URL

fix is to have CONNECT handlers just not
look at URL.

8cdee891d7 fmt: handle precision 0 format stings in standard way
The C-stdlib heritage of printf/fprintf/sprintf has two odd
aspects for precisions of zero with integers. First, the zero
can be specified in any of these ways, "%4.0d", "%.0d" and
"%.d" which was not previously supported here. Secondly, the
seemingly universal interpretation of precision for integers
is that precision==0 and value==0 means print nothing at all.
The code here now handles this for integers just as the code
in big/int.c does the same for the Int type. New tests are
added to fmt_test.go to verify these changes.

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.

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