25a01e1c3c Unify handling of caseless flag in class parser 
Apply caselessness to each element added to a class, rather than all at
finalize time (which required separated ucp dnf and-ucp working data).

Unifies the behaviour of AsciiComponentClass and Utf8ComponentClass in
this respect.

bdb7a10034 Fix defn of POSIX graph, print, punct classes 
The POSIX classes [:graph:], [:print:] and [:punct:] are handled
specially in UCP mode by PCRE. This change matches that behaviour.

abbd548899 ng_execute: update interface to use flat_set 
This changes all the execute_graph() interfaces so that instead of
mutating a std::set of vertices, they accept an initial flat_set of
states and return a resultant flat_set of states after execution.

(Note that internally execute_graph() still uses bitsets)

This is both faster and more flexible.

cf3ddd9e88 repeatStoreSparseOptimalP: make diff a u32 
As delta is a u32, we know diff will always fit within a u32 as well.
Silences a warning from Coverity.

f65170da5b cmake: improve build paths for nested builds 
If Hyperscan is built as a subproject of another cmake project, it helps to
refer to PROJECT_xx_DIR instead of CMAKE_xx_DIR, etc.

9cffa7666f Refine ComponentClass::class_empty 
ComponentClass::class_empty should only be used on finalized classes to
determine whether a given class contains any elements; it should not
take the cr_ucp or cps_ucp into account, as they have been folden in by
the finalize call.

Fixes our failure to identify that the pattern /[^\D\d]/8W can never
match.

c68bfe05d8 Don't use class_empty in early class parsing 
Instead, explicitly track whether we're still in the early class parsing
machine.

9a7b912a5d Rework parser rejection for POSIX collating elems 
Implement rejection of POSIX collating elements ("[.ch.]" and "[=ch=]"
entirely in the Ragel parser, using the same approach both inside and
ouside character classes.

Fix buggy rejection of [^.ch.], which we should accept as a character
class.

a083bcfa8d repeat: use u32 arithmetic explicitly 
In some ring-based models, we know that if the ring is not stale, then
all our bounds should fit within 32-bits. This change makes these
explicitly u32 rather than implicitly narrowing later on.
