#392494 by yched and bjaspan: Provide a query API for Field API. This is necessary because we can't assume fields will be stored in a database, due to pluggable storage backends.

- Patch #402264 by yched, bjaspan: adapt field's add-more js handler to recent fapi changes.  Added tests.

   + fixes a few missing whitelines
   + makes it clear that the same function tests field_attach_insert(), field_attach_update() and field_attach_load()
   + streamlines a few overly detailed explanations
   + add missing t() functions

- Patch #392706 by bjaspan, yched, puradata: some of the field attach tests in field.test use database queries to verify correct functionality. This makes the field attach tests work only if field_sql_module is the only field storage module in use. Instead, tests of database storage should be in the field storage module's tests, and field attach tests should operate purely at the field attach api level.

- Patch #295864 by boombatower: cleaned up the randomName() method by removing unnecessary prefix code, and added a new randomString() method which includes characters like spaces.

#376129 by boombatower, Damien Tournoud, and chx: Change getInfo() to a static method to reduce memory footprint of SimpleTest.

#369964 by yched and bjaspan: Refactor field validation and error reporting. Field API no longer coupled to Form API. Hooray.

- Patch #361683by Barry, Yves, Karen, Moshe Weitzman, David Strauss, floriant, chx, David Rothstein: initial field API patch. More work to be done, but ... oh my!
