        - removed some more unused code
        - changed quite a few more names to WebKit-style
        - moved more things out of pcre_internal.h
        - changed some indentation to WebKit-style
        - improved design of the functions for reading and writing
          2-byte values from the opcode stream (in pcre_internal.h)

        * pcre/dftables.cpp:
        (main): Added the kjs prefix a normal way in lieu of using macros.

        * pcre/pcre_compile.cpp: Moved some definitions here from pcre_internal.h.
        (errorText): Name changes, fewer typedefs.
        (checkEscape): Ditto. Changed uppercase conversion to use toASCIIUpper.
        (isCountedRepeat): Name change.
        (readRepeatCounts): Name change.
        (firstSignificantOpcode): Got rid of the use of OP_lengths, which is
        very lightly used here. Hard-coded the length of OP_BRANUMBER.
        (firstSignificantOpcodeSkippingAssertions): Ditto. Also changed to
        use the advanceToEndOfBracket function.
        (getOthercaseRange): Name changes.
        (encodeUTF8): Ditto.
        (compileBranch): Name changes. Removed unused after_manual_callout and
        the code to handle it. Removed code to handle OP_ONCE since we never
        emit this opcode. Changed to use advanceToEndOfBracket in more places.
        (compileBracket): Name changes.
        (branchIsAnchored): Removed code to handle OP_ONCE since we never emit
        this opcode.
        (bracketIsAnchored): Name changes.
        (branchNeedsLineStart): More fo the same.
        (bracketNeedsLineStart): Ditto.
        (branchFindFirstAssertedCharacter): Removed OP_ONCE code.
        (bracketFindFirstAssertedCharacter): More of the same.
        (calculateCompiledPatternLengthAndFlags): Ditto.
        (returnError): Name changes.
        (jsRegExpCompile): Ditto.

        * pcre/pcre_exec.cpp: Moved some definitions here from pcre_internal.h.
        (matchRef): Updated names.
        Improved macros to use the do { } while(0) idiom so they expand to single
        statements rather than to blocks or multiple statements. And refeactored
        the recursive match macros.
        (MatchStack::pushNewFrame): Name changes.
        (getUTF8CharAndIncrementLength): Name changes.
        (match): Name changes. Removed the ONCE opcode.
        (jsRegExpExecute): Name changes.

        * pcre/pcre_internal.h: Removed quite a few unneeded includes. Rewrote
        quite a few comments. Removed the macros that add kjs prefixes to the
        functions with external linkage; instead renamed the functions. Removed
        the unneeded typedefs pcre_uint16, pcre_uint32, and uschar. Removed the
        dead and not-all-working code for LINK_SIZE values other than 2, although
        we aim to keep the abstraction working. Removed the OP_LENGTHS macro.
        (put2ByteValue): Replaces put2ByteOpcodeValueAtOffset.
        (get2ByteValue): Replaces get2ByteOpcodeValueAtOffset.
        (put2ByteValueAndAdvance): Replaces put2ByteOpcodeValueAtOffsetAndAdvance.
        (putLinkValueAllowZero): Replaces putOpcodeValueAtOffset; doesn't do the
        addition, since a comma is really no better than a plus sign. Added an
        assertion to catch out of range values and changed the parameter type to
        int rather than unsigned.
        (getLinkValueAllowZero): Replaces getOpcodeValueAtOffset.
        (putLinkValue): New function that most former callers of the
        putOpcodeValueAtOffset function can use; asserts the value that is
        being stored is non-zero and then calls putLinkValueAllowZero.
        (getLinkValue): Ditto.
        (putLinkValueAndAdvance): Replaces putOpcodeValueAtOffsetAndAdvance. No
        caller was using an offset, which makes sense given the advancing behavior.
        (putLinkValueAllowZeroAndAdvance): Ditto.
        (isBracketOpcode): Added. For use in an assertion.
        (advanceToEndOfBracket): Renamed from moveOpcodePtrPastAnyAlternateBranches,
        and removed comments about how it's not well designed. This function takes
        a pointer to the beginning of a bracket and advances to the end of the
        bracket.

        * pcre/pcre_tables.cpp: Updated names.
        * pcre/pcre_ucp_searchfuncs.cpp:
        (kjs_pcre_ucp_othercase): Ditto.
        * pcre/pcre_xclass.cpp:
        (getUTF8CharAndAdvancePointer): Ditto.
        (kjs_pcre_xclass): Ditto.
        * pcre/ucpinternal.h: Ditto.

        * wtf/ASCIICType.h:
        (WTF::isASCIIAlpha): Added an int overload, like the one we already have for
        isASCIIDigit.
        (WTF::isASCIIAlphanumeric): Ditto.
        (WTF::isASCIIHexDigit): Ditto.
        (WTF::isASCIILower): Ditto.
        (WTF::isASCIISpace): Ditto.
        (WTF::toASCIILower): Ditto.
        (WTF::toASCIIUpper): Ditto.
