Bug 643618 - Fortran: variable with name "type" confuses Doxygen

Alternative way to get rules information from flex

This patch describes an alternative way to get rules / debug information from flex files

Most problems were solved in version 1.8.5 but the underscore character (_) had not been incorporated, this is done with this patch.

The recognition of the type (free or fixed) of Fortran code is not reliable possible. A well known possibility as used with compilers as well is to specify the type of code by means of the extension.
With EXTENSION_MAPPING it is possible to select the type of Fortran code, when not explicitly set doxygen tries to guess the type of Fortran code.

In this patch it is checked if a section label has been used before and if so a warning is given with file name and line number (when possible) where the section label was used the first time.
Note in section.h the item level was not initialized in the past in case of a copy constructor.

util/patternMatch: don't extract a QCString(QFileInfo) each time we QReg...

patternMatch iterates over the pattern list, while FileInfo remains
constant.

given this, extract the QCStrings for QFileInfo outside of the
iterating loop.

sqlite3: speedup the SELECTs

The uniqueness of rows is maintained by first doing a select.
In case the item is not found, it's INSERTed.

This is done for files, refids, params and includes, data
that is not unique by itself, like cross-references for example.
In other words, you can have many memberdefs in one file,
but you can only have one cross-reference between two functions
since the reference location is unique.

So, when SELECTing files and refids, use the file name and refids
as primary key since that's the fastest way to do it.

Also 'OR REPLACE' not necessary in 'INSERT OR REPLACE'.

In case the project logo does not exist or cannot be converted give a message instead of a white box.
Also update STR_PROJECT_LOGO in case a filename is selected that cannot be found.

include remained for debug session.

On case, on windows, more than 1 argument is given doxywizard stops without showing a message even though a printf is present.
In this patch the message is show (for all platforms) by means of a message box, furthermore in case the argument --help is given the usage message is given in a message box.

Corrected some definitions for some Fortran keywords
