Bug ?? for page numbers in the latex indices

LaTeX problem with 2 consecutive single quotes

Due to the fact that the path was not stripped from the file name in case CREATE_SUBDIRS was set to YES there was a reference to a non existing page reference. In the corresponding hypertarget and label the path was already stripped.

In LaTeX 2 consecutive single quotes are joined to 1 double quote. This leads in texts where 2 single quotes are intended to a strange view. An example is the initial value for variables. E.g. in Fortran: character(len=10) :: A = ''  (i.e an empty string which can either be defined as '' or as "") or in C: char *sq  = "''". In the source listings this is OK but in the description text it was not OK.

Remove dependency of PLantUML on HAVE_DOT

Bug 738574 - … is replaced by \cdots rather than \dots in the LaTeX output

Bug 738548 - latex: dead links to source code

Updated configuration script and libdoxygen.pro.in to use llvm-config

Last comment of \code{.f90} missing

Package mathptmx gives discrepancy between pdf and HTML formulas

Seen the discussion with the pull request 229 the dependency of PlantUML and HAVE dot should be removed.

Changed the \cdots to \dots. Based on the bug report and on http://tex.stackexchange.com/questions/77737/dots-versus-ldots-is-there-a-difference
