Some scanner errors were not checked and reported by the parser.

mapping a yaml field to an object in code has always been
a stateless operation. You could still pass state by using the
`setContext` function of the YAMLIO object, but this represented
global state for the entire yaml input. In order to have
context-sensitive state, it is necessary to pass this state in
at the granularity of an individual mapping.
This patch adds support for this type of context-sensitive state.
You simply pass an additional argument of type T to the
`mapRequired` or `mapOptional` functions, and provided you have
specialized a `MappingContextTraits<U, T>` class with the
appropriate mapping function, you can pass this context into
the mapping function.

This commit ensures that a value that's passed into YAML's IO mapOptional method
is going to be assigned a value returned by the default constructor for that
value's type when the appropriate key is not present in the YAML mapping.

Summary:
We would wrap flow mappings and sequences when they go over a hardcoded 70
characters limit. Make the wrapping column configurable (and default to 70
co the change should be NFC for current users). Passing 0 allows to completely
suppress the wrapping which makes it easier to handle in tools like FileCheck.

This commit gives the users of the YAML Traits I/O library
the ability to serialize scalars using the YAML literal block
scalar notation by allowing them to implement a specialization
of the `BlockScalarTraits` struct for their custom types.

This patch fixes a bug where the YAML Output class emitted
a sequence of flow sequences without the '-' characters.
Before:
seq:
[ a, b ]
[ c, d ]
After:
seq:
- [ a, b ]
- [ c, d ]

When reading a yaml::SequenceTraits object, YAMLIO does not report an
error if the yaml item is not a sequence. Instead, YAMLIO reads an
empty sequence. For example:
---
seq:
foo: 1
bar: 2
...
If `seq` is a SequenceTraits object, then reading the above yaml will
yield `seq` as an empty sequence.
Fix this to report an error for the above mapping ("not a sequence")

Introduce ScalarTraits::mustQuote which determines whether or not a
StringRef needs quoting before it is acceptable to output.

Don't quote octal compatible strings if they are only two wide, they
aren't ambiguous.
This reverts commit r205857 which reverted r205857.

YAMLIO would turn a BinaryRef into the string 0000000004000000.
However, the leading zero causes parsers to interpret it as being an
octal number instead of a hexadecimal one.
Instead, escape such strings as needed.

YAMLIO printed a string as is without quotes unless it contains a newline
character. That did not suffice. We also need to quote a string if it starts
with a backquote, quote, double quote or atsign, or it's the empty string.

Use memcpy to do type punning instead of a cast. A cast or similar
operation through a union breaks strict aliasing rules.
