Avoid an unnecessary serialize() call on get() requests, which makes it
faster and also happens to work around a nasty crash bug which is
causing lots of segfaults right now.
CAS semantics should be the same, if the caller handles a CAS token in
an opaque way and does not assume it is a string. I could only find one
caller of cas() in core and WMF deployed extensions, and that is
BagOStuff::mergeViaCas(), which does correctly handle CAS tokens of any
type.

Swapped some "$var type" to "type $var" or added missing types
before the $var. Changed some other types to match the more common
spelling. Makes beginning of some text in captial.
Also added some missing @param.

For caches where CAS is not natively supported, we have a workaround, where the
CAS token is (based on) the stored value.
To confirm the data can be written to cache, the CAS token is compared against
"whatever is currently in cache", so we pull the cached data and rebuild the
value.
In the case of objects, we have now pulled & rebuilt (unserialized) 2 objects
that are actually the same object (for CAS purpose - it's the correct value to
overwrite), but in terms of ===, they're 2 different values.
This patch should make sure CAS tokens are always a serialized version of the
value we're saving (where no native CAS exists); these serialized versions can
reliably be compared.

By PSR2 PHP Standard, the files should ends with exactly one newline.
Some of our files have 2 or more and some other were missing a newline.
Fix almost all occurences of CodeSniffer sniff:
PSR2.Files.EndFileNewline.TooMany
I have not fixed the selenium files, I believe we will drop them.

* merge() will use CAS if supported or use locking otherwise
* The lock()/unlock() methods now have a default implementation
* added unit tests for merge
