Node already has support for base64 encoding and decoding that is not
visible outside the string_bytes.cc file. Our work on providing a
support for the Chrome inspector protocol
(https://github.com/nodejs/node/pull/6792) requires base64 encoding
support. Rather then introducing a second copy of the base64 encoder,
we suggest moving this code into a separate header.

Calling v8::Debug::DebugBreak() directly from the signal handler is
unsafe because said function tries to grab a mutex. Work around that
by starting a watchdog thread that is woken up from the signal handler,
which then calls v8::Debug::DebugBreak().
Using a watchdog thread also removes the need to use atomic operations
so this commit does away with that.

Fix `buffer.lastIndexOf()` for the case that the first character

For example, when searching for 'abc' in 'abcdef', only the 'cdef'

Unify the common code of `Utf8Value`, `TwoByteValue`, `BufferValue`
and `StringBytes::InlineDecoder` into one class. Always make the
result zero-terminated for the first three.
This fixes two problems in passing:
* When the conversion of the input value to String fails,
make the buffer zero-terminated anyway. Previously, this would
have resulted in possibly reading uninitialized data in multiple
places in the code. An instance of that problem can be reproduced
by running e.g.
`valgrind node -e 'net.isIP({ toString() { throw Error() } })'`.
* Previously, `BufferValue` copied one byte too much from the source,
possibly resulting in an out-of-bounds memory access.
This can be reproduced by running e.g.
`valgrind node -e \
'fs.openSync(Buffer.from("node".repeat(8192)), "r")'`.
Further minor changes:
* This lifts the `out()` method of `StringBytes::InlineDecoder`
to the common class so that it can be used when using the
overloaded `operator*` does not seem appropiate.
* Hopefully clearer variable names.
* Add checks to make sure the length of the data does not exceed
the allocated storage size, including the possible null terminator.

It is useful if you have a handle, even if it has been closed, to be
able to inspect whether that handle was unrefed or not. As such, this
renames the method accordingly. If people need to check a handle's
aliveness, that is a separate API we should consider exposing.

node_buffer.cc, where PatternChar and SubjectChar are always the same. Since
this is extra complexity that's unused and untested (simplifying to a single
Char template argument still compiles and didn't break any unit tests), I
removed it.
