internals: document CBOR utilization

I spoke with some people at Mozilla about CBOR and they advised me
that we should be careful about the subset of CBOR we use in order
to mitigate security, performance, and compatibility concerns.

This commit establishes a document that attempts to formalize our
use of CBOR.

Its main limitations are on what types are allowed. It explicitly
enumerates which types are supported. Notable missing features
include:

* Indefinite-length arrays and maps
* Text strings (bytes all the way)
* Floats
* Date/time types
* Big integers
* Use of indefinite-length byte strings for map keys, values in
  containers.

If we have a need for any of these, we can have a discussion about
them when the time comes.

A fix with a single line results in a bullet point in the appropriate section

  $ touch fix1
  $ hg -q commit -A -l - << EOF
  > single line fix
  > 
  > .. fix::
  > 
  >    Simple fix with a single line content entry.
  > EOF

  $ hg releasenotes -r . $TESTTMP/relnotes-single-line

  $ cat $TESTTMP/relnotes-single-line
  Bug Fixes
  =========
  
  * Simple fix with a single line content entry.

A fix with multiple lines is handled correctly

  $ touch fix2
  $ hg -q commit -A -l - << EOF
  > multi line fix
  > 
  > .. fix::
  > 
  >    First line of fix entry.
  >    A line after it without a space.
  > 
  >    A new paragraph in the fix entry. And this is a really long line. It goes on for a while.
  >    And it wraps around to a new paragraph.

  $ cat $TESTTMP/relnotes-multi-line
  Bug Fixes
  =========
  
  * First line of fix entry. A line after it without a space.
  
    A new paragraph in the fix entry. And this is a really long line. It goes on
    for a while. And it wraps around to a new paragraph.

A release note with a title results in a sub-section being written

  $ touch fix3
  $ hg -q commit -A -l - << EOF
  > fix with title
  > 
  > .. fix:: Fix Title
  > 
  >    First line of fix with title.
  > 
  >    Another paragraph of fix with title. But this is a paragraph
  >    with multiple lines.

  $ hg releasenotes -r . $TESTTMP/relnotes-fix-with-title
  $ cat $TESTTMP/relnotes-fix-with-title
  Bug Fixes
  =========
  
  Fix Title
  ---------
  
  First line of fix with title.
  
  Another paragraph of fix with title. But this is a paragraph with multiple
  lines.

Formatting of multiple bullet points works

  $ hg init multiple-bullets
  $ cd multiple-bullets
  $ touch fix1
  $ hg -q commit -A -l - << EOF
  > commit 1
  > 
  > .. fix::
  > 
  >    first fix
  > EOF

  $ touch fix2
  $ hg -q commit -A -l - << EOF
  > commit 2
  > 
  > .. fix::
  > 
  >    second fix
  > 
  >    Second paragraph of second fix.
  > EOF

  $ touch fix3
  $ hg -q commit -A -l - << EOF
  > commit 3
  > 
  > .. fix::
  > 
  >    third fix
  > EOF

  $ hg releasenotes -r 'all()' $TESTTMP/relnotes-multiple-bullets
  $ cat $TESTTMP/relnotes-multiple-bullets
  Bug Fixes
  =========
  
  * first fix
  
  * second fix
  
    Second paragraph of second fix.

Formatting of multiple sections works

  $ hg init multiple-sections
  $ cd multiple-sections
  $ touch fix1
  $ hg -q commit -A -l - << EOF

  $ touch feature1
  $ hg -q commit -A -l - << EOF
