Hashtable is arranged as an array of
8-entry buckets with chained overflow.
Each bucket has 8 extra hash bits
per key to provide quick lookup within
a bucket.  Table is grown incrementally.

debugging Issue 4183

Unfortunately this package lacks testing around this,
or most of child.go. :/

Fixes #5085.

{6,8}c/swt.c allocates a third Biobuf in automatic memory which is not terminated at the end of the function. This causes the buffer to be 'in use' when the batexit handler fires, confusing valgrind.

Huge thanks to DMorsing for the diagnosis.

Inserting a key-value pair into a hashmap storing keys or values
indirectly can cause the garbage collector to find the hashmap in

- A note doesn't have to be in the first
comment of a comment group anymore, and
several notes may appear in the same comment
group (e.g., it is fairly common to have a
TODO(uid) note immediately following another
comment).

- Define a doc.Note type which also contains
note uid and position info.

- Better formatting in godoc output. The position
information is not yet used, but could be used to
locate the note in the source text if desired.

Fixes #4843.

godef[1][2] is a third party tool for printing information about
expressions, especially the location of their definition. This can be
used to implement a "jump to definition" function. Unlike
cross-language solutions like ctags, godef does not require an index,
operates on the Go AST instead of symbols and works across packages,
including the standard library.

This patch implements two new public functions: godef-describe (C-c
C-d) and godef-jump (C-d C-j). godef-describe describes the expression
at point, printing its type, and godef-jump jumps to its definition.
