Move parser + parser tests out to own package.

We move some types out that are necessary as well and then
re-export and specialise them in the core Haddock.

Reason for moving out spec tests is that if we're working on the parser,
we can simply work on that and we can ignore the rest of Haddock. The
downside is that it's a little inconvenient if at the end of the day we
want to see that everything passes.

--- $parsec
---
--- Compared to Parsec 3, Attoparsec makes several tradeoffs.  It is
--- not intended for, or ideal for, all possible uses.
---
--- * While Attoparsec can consume input incrementally, Parsec cannot.
---   Incremental input is a huge deal for efficient and secure network
---   and system programming, since it gives much more control to users
---   of the library over matters such as resource usage and the I/O
---   model to use.
---
--- * Much of the performance advantage of Attoparsec is gained via
---   high-performance parsers such as 'I.takeWhile' and 'I.string'.
---   If you use complicated combinators that return lists of bytes or
---   characters, there is less performance difference between the two
---   libraries.
---
--- * Unlike Parsec 3, Attoparsec does not support being used as a
---   monad transformer.
---
--- * Attoparsec is specialised to deal only with strict 'B.ByteString'
---   input.  Efficiency concerns rule out both lists and lazy
---   bytestrings.  The usual use for lazy bytestrings would be to
---   allow consumption of very large input without a large footprint.
---   For this need, Attoparsec's incremental input provides an
---   excellent substitute, with much more control over when input
---   takes place.  If you must use lazy bytestrings, see the 'Lazy'
---   module, which feeds lazy chunks to a regular parser.
---
--- * Parsec parsers can produce more helpful error messages than
---   Attoparsec parsers.  This is a matter of focus: Attoparsec avoids
---   the extra book-keeping in favour of higher performance.
-
--- $incremental
---
--- Attoparsec supports incremental input, meaning that you can feed it
--- a bytestring that represents only part of the expected total amount
--- of data to parse. If your parser reaches the end of a fragment of
--- input and could consume more input, it will suspend parsing and
--- return a 'T.Partial' continuation.
---
--- Supplying the 'T.Partial' continuation with another bytestring will
--- resume parsing at the point where it was suspended. You must be
--- prepared for the result of the resumed parse to be another
--- 'T.Partial' continuation.
---
--- To indicate that you have no more input, supply the 'T.Partial'
--- continuation with an empty bytestring.
---
--- Remember that some parsing combinators will not return a result
--- until they reach the end of input.  They may thus cause 'T.Partial'
--- results to be returned.
---
--- If you do not need support for incremental input, consider using
--- the 'I.parseOnly' function to run your parser.  It will never
--- prompt for more input.
-
--- $performance
---
--- If you write an Attoparsec-based parser carefully, it can be
--- realistic to expect it to perform within a factor of 2 of a
--- hand-rolled C parser (measuring megabytes parsed per second).
---
--- To actually achieve high performance, there are a few guidelines
--- that it is useful to follow.
---
--- Use the 'B.ByteString'-oriented parsers whenever possible,
--- e.g. 'I.takeWhile1' instead of 'many1' 'I.anyWord8'.  There is
--- about a factor of 100 difference in performance between the two
--- kinds of parser.
---
--- For very simple byte-testing predicates, write them by hand instead
--- of using 'I.inClass' or 'I.notInClass'.  For instance, both of
--- these predicates test for an end-of-line byte, but the first is
--- much faster than the second:
---
--- >endOfLine_fast w = w == 13 || w == 10
--- >endOfLine_slow   = inClass "\r\n"
---
--- Make active use of benchmarking and profiling tools to measure,
--- find the problems with, and improve the performance of your parser.

--- $encodings
---
--- This module is intended for parsing text that is
--- represented using an 8-bit character set, e.g. ASCII or
--- ISO-8859-15.  It /does not/ make any attempt to deal with character
--- encodings, multibyte characters, or wide characters.  In
--- particular, all attempts to use characters above code point U+00FF
--- will give wrong answers.
---
--- Code points below U+0100 are simply translated to and from their
--- numeric values, so e.g. the code point U+00A4 becomes the byte
--- @0xA4@ (which is the Euro symbol in ISO-8859-15, but the generic
--- currency sign in ISO-8859-1).  Haskell 'Char' values above U+00FF

--- | The core parser type.  This is parameterised over the type @t@ of
--- string being processed.
---
--- This type is an instance of the following classes:
---
--- * 'Monad', where 'fail' throws an exception (i.e. fails) with an
---   error message.
---
--- * 'Functor' and 'Applicative', which follow the usual definitions.
---
--- * 'MonadPlus', where 'mzero' fails (with no error message) and
---   'mplus' executes the right-hand parser if the left-hand one
---   fails.  When the parser on the right executes, the input is reset
---   to the same state as the parser on the left started with. (In
---   other words, Attoparsec is a backtracking parser that supports
---   arbitrary lookahead.)
---
--- * 'Alternative', which follows 'MonadPlus'.
