2015-11-17, Version 5.1.0 (Stable)

Notable changes:

* buffer: The `noAssert` option for many buffer functions will now silently drop invalid write values rather than crashing (P.S.V.R) #3767.
  - This makes the behavior match what the docs suggest.
* child_process: `child.send()` now properly returns a boolean like
the docs suggest (Rich Trott) #3577.
* doc: All of the API docs have been re-ordered so as to read in alphabetical order (Tristian Flanagan) #3662.
* http_parser: update http-parser to 2.6.0 from 2.5.0 (James M
Snell) #3569.
  - Now supports the following HTTP methods: `LINK`, `UNLINK`, `BIND`,
`REBIND`, `UNBIND`.
  - Also added ACL and IPv6 Zone ID support.
* npm: upgrade npm to 3.3.12 from v3.3.6 (Rebecca Turner)
#3685.

* repl: The REPL no longer crashes if the persistent history file
cannot be opened (Evan Lucas) #3630.
* tls: The default `sessionIdContext` now uses SHA1 in FIPS mode rather than MD5 (Stefan Budeanu) #3755.
* v8: Added some more useful post-mortem data (Fedor Indutny) #3779.
