Bug 735481 - [PATCH] Mismatch in memory allocation/de-allocation function in vhdlparser/vhdlstring.h

Create an easy possibility to take a snippet from the current file.

Better handling of inline Fortran parameter documentation

Bug 651859 - Brief description misplaced in man page output

Also fixed a parse error when reading a tag file with a Java-style enum

Bug 651850 - @defgroup generates manpage warning

In case the comment for Fortran arguments is empty or just contains @param [direction] <varname> or parts of these. The comment is is not shown and (depending on the configuration settings, a warning is given).
Also the detection of inconsistencies between intent attribute and documentation has been improved.

In case the \cite command is used but no entry for it is given in a bib file no warning is given as the CiteInfo entry is present with the right label, but the text item is empty and this is not tested.

(also corrected an error message on opening a file)

Merge branch 'feature/bug_700510' of https://github.com/albert-github/doxygen into albert-github-feature/bug_700510

Changed the previous fix to allow references to sections defined in
a mainpage that is imported via a tag file.

Correction of typing error

Corrected documenation -> documentation

Support multiple extra HTML stylesheets.

In case the snippet of code is in the current file one has to specify the name of the file and also see to it that the file is reachable through the EXAMPLE_PATH.
A use case is the case of a list of initial values here it is quite often more convenient to have the values listed in a 'nice' list than direct in the definition line.
With this patch it is possible to specify the name of the file where the snippet resides as: this

In regular use it happens that it is more convenient to have multiple extra HTML stylesheets, e.g. in case of different levels of requirements: company, department, project
With this patch it is possible to specify multiple HTML stylesheets.
Note: for compatibility the configuration parameter HTML_EXTRA_STYLESHEET has not been renamed to HTM_EXTRA_STYLESHEETS.
