Track the typical #ifndef/#define/#endif usage in header files to see if
the macro is an include guard. If so, store it in the Document. No
behavioural change, just recording the name.

This can be used in the future to track if a file needs to be re-parsed
when a macro changes: if it was used in the file, and not defined in it
nor being the include-guard, a file should be re-preprocessed and
re-parsed.

It can also be used to check if two files have the same include guard.

Summary of most relevant items:

- Preprocessor output format change. No more gen true/false. Instead
  a more intuitive and natural expansion (like from a real compiler) is
  performed directly corresponding to the macro invocation. Notice that
  information about the generated tokens is not lost, because it's now
  embedded in the expansion section header (in terms of lines and columns
  as explained in the code). In addition the location on where the macro
  expansion happens is also documented for future use.

- Fix line control directives and associated token line numbers.
  This was not detected in tests cases because some of them were
  actually wrong: Within expansions the line information was being
  considered as originally computed in the macro definition, while
  the desired and expected for Creator's reporting mechanism (just
  like regular compilers) is the line from the expanded version
  of the tokens.

- Do not allow for eager expansion. This was previously being done
  inside define directives. However, it's not allowed and might
  lead to incorrect results, since the argument substitution should
  only happen upon the macro invocation (and following nested ones).
  At least GCC and clang are consistent with that. See test case
  tst_Preprocessor:dont_eagerly_expand for a detailed explanation.

- Revive the 'expanded' token flag. This is used to mark every token
  that originates from a macro expansion. Notice, however, that
  expanded tokens are not necessarily generated tokens (although
  every generated token is a expanded token). Expanded tokens that
  are not generated are those which are still considered by our
  code model features, since they are visible on the editor. The
  translation unit is smart enough to calculate line/column position
  for such tokens based on the information from the expansion section
  header.

- How expansions are tracked has also changed. Now, we simply add
  two surrounding marker tokens to each "top-level" expansion
  sequence. There is an enumeration that control expansion states.
  Also, no "previous" token is kept around.

- Preprocessor client methods suffered a change in signature so
  they now receive the line number of the action in question as
  a paramater. Previously such line could be retrieved by the client
  implementation by accessing the environment line. However, this
  is not reliable because we try to avoid synchronization of the
  output/environment lines in order to avoid unnecessary output,
  while expanding macros or handling preprocessor directives.

- Although macros are not expanded during define directives (as
  mentioned above) the preprocessor client is now "notified"
  when it sees a macro. This is to allow usage tracking.

- Other small stuff.

This is all in one patch because the fixes are a consequence
of the change in preprocessing control.
