TIFFTAG_NUMBEROFINKS value
In order to solve the buffer overflow issues related to TIFFTAG_INKNAMES and related TIFFTAG_NUMBEROFINKS value, a revised handling of those tags within LibTiff is proposed:
Behaviour for writing:
`NumberOfInks` MUST fit to the number of inks in the `InkNames` string.
`NumberOfInks` is automatically set when `InkNames` is set.
If `NumberOfInks` is different to the number of inks within `InkNames` string, that will be corrected and a warning is issued.
If `NumberOfInks` is not equal to samplesperpixel only a warning will be issued.
Behaviour for reading:
When reading `InkNames` from a TIFF file, the `NumberOfInks` will be set automatically to the number of inks in `InkNames` string.
If `NumberOfInks` is different to the number of inks within `InkNames` string, that will be corrected and a warning is issued.
If `NumberOfInks` is not equal to samplesperpixel only a warning will be issued.
This allows the safe use of the NumberOfInks value to read out the InkNames without buffer overflow
This MR will close the following issues: #149, #150, #152, #168 (to be checked), #250, #269, #398 and #456.
It also fixes the old bug at http://bugzilla.maptools.org/show_bug.cgi?id=2599, for which the limitation of `NumberOfInks = SPP` was introduced, which is in my opinion not necessary and does not solve the general issue.
