* avoid re-declaration of constant variables

* Replace pthreads critical section with std::mutex

* ci - better naming

* cmake - increase minimum version to 3.11. Use project DESCRIPTION

* fix - do not treat string::find() return type as bool

* remove conditions that were always true

* Remove EXV_HAVE_GMTIME_R which is not used anymore

* pixelWidth_ was inherited from Exiv2::Image

The width & height variables in the TiffImage class need to be mutable
to be able to change their values on the getters pixelHeight() and
pixelWidth() ... Do not ask me why ...

* Remove superfluous if

* pvs:V766 item with identical key added already

* pvs:V730 not all members were initialized (time)

* pvs:V730 not all members are initialized

* pvs:V1048 variable assigned the same value

* replace c-style dynamic vector with std one

* pvs:547 fakeData is always true

* Remove useless constructor in derived class

* pvs:V690 modern way to disable copy-ctor

* Remove custom MIN/MAX functions

* pvs:V595 pointer used before verified against null

* pvs: index used before being checked

* pvs:V1028 possible overflow. Cast operands

* pvs:v575 potential null pointer passed to other functions

* pvs:V547 deal with always true/false expressions

* pvs:V560 part of conditional expressions always false or true

* pvs:V701 possible break in realloc -> move to std::vector

* Make some classes 'final'

ecaf1dd478 Fix alpha bit detection in VP8L chunks 
As per the spec ([1]), the alpha_bit is located on the 4th byte of the payload, just after the height.

This seems to fix the bug reported on GIMP ([2]) where an incorrect file was generated.

fec6535ae8 [binaryToString] Reimplement using Slices 
- reimplement binaryToString:
  - it now accepts a Slice and nothing else
  - it does not return a std::string but instead a proxy object that implements
    operator<< (this should be more efficient, as we do not need to touch the
    heap in most cases)
- addapt unit tests
- replace all occurences with the new API

1ab921cb83 Add two padding bytes to exifLongHeader to prevent overreads 
in the following call:
getHeaderOffset (payload.pData_, payload.size_, (byte*)&exifLongHeader, 6);

getHeaderOffset would read 6 bytes from exifLongHeader, reading beyond the
bounds of the array => add 2 padding bytes to prevent overreads
