6dfb6a3016 imgcodecs: fix RBaseStream::setPos() outside of current block
Seeking outside of the current block doesn't update actual data,
so getByte()/etc will get wrong data from stalled buffer.

e6c41f0de6 Merge pull request #12989 from venalil:fix_thresholded_tiff_read
* Fix reading of black-and-white (thresholded) TIFF images

I recently updated my local OpenCV version to 3.4.3 and found out that
I could not read my TIFF images related to my project. After debugging I
found out that there has been some static analysis fixes made
that accidentally have broken reading those black-and-white TIFF images.

Commit hash in which reading of mentioned TIFF images has been broken:
cbb1e867e5

Basically the fix is to revert back to the same functionality that has been there before,
when black-and-white images are read bpp (bitspersample) is 1.
Without the case 1: this TiffDecoder::readHeader() function always return false.

* Added type and default error message

* Added stdexcept include

* Use CV_Error instead of throw std::runtime_error

* imgcodecs(test): add TIFF B/W decoding tests

fix some errors found by static analyzer. (#12391)

* fix possible divided by zero and by negative values

* only 4 elements are used in these arrays

* fix uninitialized member

* use boolean type for semantic boolean variables

* avoid invalid array index

* to avoid exception and because base64_beg is only used in this block

* use std::atomic<bool> to avoid thread control race condition

0515f930e8 imgcodecs(webp): multiple fixes
- don't reallocate passed 'img' (test fixed - must use IMREAD_UNCHANGED / IMREAD_ANYCOLOR)
- avoid memory DDOS
- avoid reading of whole file during header processing
- avoid data access after allocated buffer during header processing (missing checks)
- use WebPFree() to free allocated buffers (libwebp >= 0.5.0)
- drop unused & undefined `.close()` method
- added checks for channels >= 5 in encoder

9f5f64e14e Merge pull request #12192 from pasbi:pfm
* created new decoder and encoder for PFM

pfm file format stores binary RGB or grayscale float images.

* added test for pfm codec

* replaced large with short licence header

* little/big-endian-check is now compile time

* fixed width/height confusion, improved big/little endian recognition, fixed scaling issue and Improved signature check

* adapted tests to handle float images well

* removed data-dependency: lena.pfm

the lena image is now loaded is pam and converted to pfm.

* fixed bug in endianess detection macro

* Added endianess detection for android and win

* removed fancy endianess detection

endianess detection will be implemented in cmake scripts soonish.

* fixed minor warnings

* fixed stupid elif defined bug

* silenced some implicit cast warnings

* replaced std::to_string with std::stringstream solution

std::to_string variant did not build on android.

* replaced new endianess macros with existing ones

* improved readability
