e5eab182b5 Use boost::variant to represent shielded addresses and keys 
libzcash::PaymentAddress has been renamed to libzcash::SproutPaymentAddress,
and a new typedef boost::variant is now libzcash::PaymentAddress. Similarly
for ViewingKey and SpendingKey.

A new class InvalidEncoding is introduced as the default boost::variant
option for each address and key type; it is used during decoding instead
of boost::optional.

All address and key storage functions in the wallet have been modified to
refer specifically to the Sprout types, as they are used very precisely.
In most other cases, the more general type is leveraged as much as possible,
and we convert to the Sprout type when necessary. This will be subsequently
wrapped in, or replaced with, context-specific functions once Sapling
types are implemented.

Make some globals static that can be

I wrote this patch as part of making a Bazel build system but it really is independent from that so I'm putting this as a separate PR.

External linkage does not help and just encourages sloppy dependencies (ie using symbols only declared in a cpp file in some other cpp file) and can lead to weird issues when there are name collisions.

5d99e3e92f Refactoring: SproutNote member variable value moved to BaseNote. 
All notes have a value, so the member variable has been moved to the
base class, and direct member access has been replaced with a getter.

4e4aa5b6ec Get rid of underscore prefixes for include guards. 
This is because they may conflict with reserved names. Also took
this opportunity to make the guards in the zcash subdir a bit
more uniform by having them all conform to ZC_<...>_H_

Improve joinsplit diagnostics

I don't advocate merging this for the hotfix release (to fix #1779) but this PR can be used to diagnose the real issue and should be merged ASAP afterward.

~I still need to add tests for `last()` and `element()` though.~ Done.
