Fix for when transformer block rejects a pulled doc

Needed to mark the doc's sequence as no longer pending. Otherwise the
checkpoint doesn't advance, and the puller will keep trying to pull that
doc on subsequent runs.
Fixed another assertion-failure when a _bulk_get download can’t parse a JSON doc

Found a piece that was missing from the prior fix 24f6381. The same assertion failure was occurring,
under slightly different circumstances.
Fixes #288 (speculatively). Also see #271, #232.
Tweaked some logging in CBLReplication.m.
Finally fixed the multipart JSON-decoding bugs

Fixes #288
Fixes #289
Tweaked logging in CBLReplication.m some more.
Declare public C functions as `extern “C”` when compiled in C++ mode

Otherwise Obj-C++ apps get link errors using functions like CBLTextKey.
Fixes #291
Back to $ARCHS_STANDARD for iOS builds

Removes the “Release-64bit” build configuration.
With Xcode 5.1+, the regular iOS frameworks will include 64-bit.
With earlier Xcodes only 32-bit.
NOTE: This commit breaks the automated Jenkins build.
The build script will need to remove the steps to build with Release-64bit,
and to copy extra 64-bit frameworks.
Added CBLIncrementalStore source files to Extras

The “Extras” folder generated by the iOS build target now includes CBLIncrementalStore.{h,m}.
Also, the README in that folder has been updated to describe it.
Fixed -[CBLDatabase existingDocumentWithID:] not returning nil for nonexistent doc

(Reported in post to mailing list)
Reduced max memory usage of push replicator

- Added some fixes to avoid keeping redundant data in memory
- Constrained max size of a _bulk_docs request to keep the object tree from getting too large
Fixes #270
Removed “Slow comparison” log message from JSON collator

This wasn’t supposed to be checked in…
