Stefan Weil 948332e6ed Fix some potential overflow issues (#1161)
* Fix some potential overflow issues

Put sizeof to the beginning of the multiplication to enforce that
size_t instead of smaller integer types is used for the calculation.

This fixes warnings from LGTM:

    Multiplication result may overflow 'unsigned int'
    before it is converted to 'unsigned long'.

It also allows removing some type casts.

Even Rouault af76000771 tiftoimage(): fix read heap buffer overflow (#988)
The number of components is given only by TIFFTAG_SAMPLESPERPIXEL / tiSpp.
Querying TIFFTAG_EXTRASAMPLES only give information about which channel is
the alpha channel, but we mostly ignore it for now, so remove that part of the
code.
