file_systems & Tracker: Do not assume sizeof(dirent) contains 1 byte for the name.

At present, it does, but that is an oddity we have preserved from BeOS
that the next commit is going to remove. (This commit thus wastes 1 byte
without the following one.)

Most changes are pretty straightforward: only a +1 is needed,
and a few removed from sizing calculations. Some filesystems like UDF
originally passed back the length with the \0 included, so they have
been adjusted further. UFS2 had some other sizing problems which are also
corrected in this commit.

bfs: Use the QueryParserUtils instead of its own copy.

* Ingo copied the methods into a shared location, and then obviously
"forgot" to let BFS use them. As a side note for Ingo: the complete
error GCC reported was "std::fssh_size_t" not defined with the macro
wrapper as code location. The actual problem was a "using std::size_t"
in some C++ header that accidentally got included after the wrapper.
* The shared Query code is not yet used. That'll be done another time.
* Renamed BFS_SHELL define to FS_SHELL, such that QueryParserUtils can be
used in any file system shell, not just the bfs_shell.

QueryParser: Equation::Match(): Fix generic attribute case

Init size to the buffer size before passing it to
QueryPolicy::NodeGetAttribute(). Since size was 0 by default, we would
only read 0 length data.

QueryParser: Fix some debug macros

Move B_MIME_STRING_TYPE to <TypeConstants.h>

Move helper function out of QueryParser.h

They live in the new QueryParserUtils.{h,cpp} now.

QueryParser: The last_modified index is time_t

* Changed value type from B_INT64_TYPE to B_INT32_TYPE.
* Changed QueryPolicy::NodeGetLastModifiedTime() return value from
bigtime_t to time_t.

Small cleanup

QueryParser: Explicitly suspend/resume iterators

Extended policy by IndexIteratorSuspend() and IndexIteratorResume()
methods that are invoked for the index iterator by Query::GetNextEntry()
after entering respectively before exiting.

Create a generalized version of BFS's query code

The new version is templatized over a QueryPolicy which provides the
interface to the file system specifics.
