4bb4d392e4 Remove limit on the number of backrefs possible. 
Changes named sub-expressions to use different hashing scheme: high order bit is now always set to clashes between hashes and indexes don't happen until 2^30 or 2^62 sub-expressions in 32 and 64 bit code respectively.
Changes bitmask of seen sub-expressions to use dynamic storage for sub-expression indexes above 64.
Adds tests for the above.
Fixes https://github.com/boostorg/regex/issues/75.

3168641320 Avoid generating pointers in writeable data section. 
They increase memory consumption and make exploits
easier and are completely unnecessary.
Avoid them by either avoiding the pointer indirection
completely by using char arrays for strings instead
of char pointers, convert "static" pointer variables
to simple local variables, or mark the array of
pointers as const instead of just the things pointed to.

6ffcc5ede0 Change detail namespace. 
Big search and replace to change name of internal namepace so it's mangled with the Boost version number - the aim is to reduce the chances of mixing different header and library versions.

1b8322ecbf fix trac 9544: gcc 4.9.0 -std=c++1y breakage

one is (probably) not.
