Writer flush api

Issue 889 pretty writer

Missed PrettyWriter in the initial fix for Issue #889

This is helpful if you’re writing code that needs to control flush
behavior and you don’t want to pass around your buffer object to each
handler function alongside the writer. Seems like an easy convenience
to add.

Merge back

v_ has a value assigned to it as part of ParseNext() which happens in
the constructor, but that’s not soon enough for GCC

GCC and Clang cannot agree on what constitutes a good switch statement.

Issue 889

Fix clang -Wswitch-enum warnings.
Made NextArrayValue() more robust—now handles error state correctly,
will enter error state if an unexpected state is reached.
Made separate states for each value type to simplify getters.
Simplified implementation of skipping arrays and objects.
Skipping an object now works whether you’ve retrieved the key or not.

It did not support char arrays.
