Print debug stacktraces from within a forked worker

Fixes CHEF-4357: http://tickets.opscode.com/browse/CHEF-4357

Rescue exceptions from within a forker worker and feed them to
`Chef::Application.debug_stacktrace()`, then exit non-zero. This fixes
an issue where Chef would spew ruby stacktraces with forking enabled
(stacktraces should only be printed to console with `-l debug`).
Additionally fixes an issue where a generic exception was passed to
`debug_stacktrace`, leaving a stacktrace.out file with no useful
information.

In addition to the above fixes, includes the following improvements:
* Update the forked worker's argv0 to clearly indicate it's the worker
  process, and include ppid and run start time.
* When reaping the worker process, include more useful information when
  the worker exited non-successfully, such as exit code or signal that
  killed the process. In particular, OOM kill (e.g., when running
  resource intensive code compile, etc. on small machine) should be a
  little more obvious.
Exit worker process on INT/TERM

Merge pull request #882 from opscode/default-yum-timeout

Increase the default yum timeout to 5 minutes.
Change error description sections elements to be hashes.

It is much easier for erlang to validate the json that chef-client sends up if exception_data.description.sections is of structure:

[{"str1" => "value1"}, ... ]

As opposed to current structure of:

[["str1", "value1"], ... ]

This change was achieved by updating error_description.rb. I also updated relevant test.
Add -E flag to chef-solor so that users can make use of environments with chef-solo.
Ignore corrupt cache control data; re-download file

Fixes CHEF-4365: http://tickets.opscode.com/browse/CHEF-4365

A corrupt cache control file will cause a persistent failure of the
related remote_file resource. Since this data is just a cache of HTTP
headers, Chef can ignore corrupted cache control data, re-download the
source file, and then re-populate the cache with not-corrupt data.
