 [patch] analyze minimum needed number of null separators in
 PngChunk::parseTXTChunk

This commit fixes the heap-buffer-overflow in PngChunk::parseTXTChunk.

According to the specification:
http://www.libpng.org/pub/png/spec/1.2/PNG-Chunks.html

There must be 2 null separators when we start to analyze the language tag.

 [patch] catch all exceptions not caught in exiv2 cli-tool

It effectively looks the same as before, only now we don't call abort() but
instead clean up everything gracefully.

 [patch] add offset_ and size_ safely in
 LoaderExifJpeg::LoaderExifJpeg

offset_ can become arbitrarily large and overflows once its added to size_,
this causes all kinds of problems further in the code when offset_ is used
again.
=> Use Safe::add() to catch potential overflows
This fixes #365.

 [patch] fix addition overflows in range checks in loadertiff::getdata

Several checks for extracted values performed no overflow checks on the
addition. They can be tricked into passing, albeit the individual summands are
too large.
=> use Safe::add() which now aborts when an overflow occurs
This fixes #366

 [patch] add overflow & overread checks to pngchunk::parsetxtchunk()

This function was creating a lot of new pointers and strings without
properly checking the array bounds. This commit adds several calls
to enforce(), making sure that the pointers stay within bounds.
Strings are now created using the helper function
string_from_unterminated() to prevent overreads in the constructor of
std::string.

This fixes #400
