This includes a simplified resolvePath function and tests for all normal and abnormal path resolution examples described in RFC 3986, sections 5.4.1 and 5.4.2 [1]. Some of those examples failed before (see http://play.golang.org/p/F0ApSaXniv).

Also, parsing a reference "//foo" now works as expected. It was treated as an absolute path with very weird results (see http://play.golang.org/p/089b-_xoNe).

During path resolution, all dot segments are removed as described by the RFC.

A few existing tests had to be changed because they expected the wrong output.

Fixes #4700.

Fixes #4706.

"go build" and "go install" were mixing stdout and stderr
from the toolchain, then putting it all on stdout. With this
change, it stays mixed, and is sent to stderr. Because
the toolchain does not create output in a clean compile/install,
sending all output to stderr makese more sense.

Also fix test.bash because of "mktemp: too few X's
in template `testgo'" on Linux.

This brings Mach-O generation more in line with ELF generation.

Having separate sections for the symtab and pclntab mean that we
can find them that way, instead of using the deprecated debug segments.
(And the host linker will keep separate sections for us, but probably
not the debug segments.)

Previously it was evaluated once, so re-using the timeout option
repeatedly would always generate the same deadine.

The sticking point on 386 has been the "PC relative" relocations
used to point the garbage collection metadata at the type info.
These aren't in the code segment, and I don't trust that the linker
isn't doing something special that would be okay in code but
not when interpreting the pointers as data (for example, a PLT
jump table would be terrible).

Solve the problem in two steps:

1. Handle "PC relative" relocations within a section internally,
so that the external linker never sees them.

2. Move the gcdata and gcbss tables into the rodata section,
where the type information lives, so that the relocations can
be handled internally.

(To answer the obvious question, we make the gc->type
references relative so that they need not be relocated
individually when generating a shared object file.)

For  better printing, I recently changed Name to return "<unnamed>" for templates
with empty names, but this causes trouble for the many packages that used "" as
the template name, so restore the old behavior.
It's usually printed as a quoted string anyway, so it should be fine.
