Debug output for lexical analyzer

In case of error messages like:
    input buffer overflow, can't enlarge buffer because scanner uses REJECT
it is not always directly clear from which lexical analyzer (.l file) this problem comes.
This patch helps to find these problems and does the following things:
- when using the option -d lex with doxygen each time a lexical analyzer is called at the start a line like the following line will be given:
    Entering lexical analyzer: pre.l (for: ..../file.c)
  and at the end:
    Finished lexical analyzer: pre.l (for: ..../file.c)
- in case the lexical analyzer has been translated with the -d option of lex / flex the above mentioned lines will be given as part of the lexical analyzer output (to stderr) and look like:
    --entering lexical analyzer: pre.l (for: ..../file.c)
    --finished lexical analyzer: pre.l (for: ..../file.c)

Space missing in error message.

Bug 711787 - Long initialization line in C stops doxygen

the word 'in' and the vale of filesOption were concatenated

An extra "breakpoint" in the input string has been created in the form of a , (comma), so for initialization lines the line will be shorter and the , (comma) will be copied later on.

consistency 0bj -> ../../objects

- Doxygen.sln
build doxygen 64 bit debug too

Config was missing (cannot be automatic due to the fact that there are 2 rules in 1 file), see also Doxywizard.vcproj

Esperanto not supported by htmlhelp compiler

reverting for esperanto to default language (US English)

Doxysearch under Cygwin should not have extension cgi.exe but just .cgi

Build problem with unistd.h and Cygwin

The standard g++ compiler under windows (win32-g++) has unistd.gh file; Microsoft windows does not have it, therfore it is better to use the winbuild directory in case of windows adn no dependency otherwise

Patch regarding generating the rules file for the windows build regardin...

bug_647517  - make install prepends a slash to the installation path

Patch regarding generating the rules file for the windows build regarding languages, some inconsistencies in the (windows) build system, corrections to some spelling.

- maintainers.txt
Spelling correction

- config.xml
Added missing languages
Extended some descriptions

- htmlhelp.cpp
Added missing languages
Spelling corrections

Corrected some incorrect references / directories
Corrected names of generated files / directories so they won't overwrite / conflict (especially during parallel builds)
Note place of resulting executable has hanged (more consistent now)

- Settings.rules
Corrected place where configure file can be found

- lang_cfg.py
Script to generate the file lang_cfg.h based on the specified languages in the windows GUI or in the configure script.

- languages.py
Script to generate languages pane in the windows GUI
This file has to be called outside visual studio as it generates the rules for the Languages pane in the GUI (command on src directory python languages.py > ..\winbuild\Languages.rules)

- Languages.rules
Result file from language.py (old file was completely wrong and not used)
This file has to be generated outside visual studio as it contains the rules for the Languages pane in the GUI

- configure
Use lang_cfg.py script (consistency) instead of (internal) perl script.

Removed superfluous /
