• add manufacturer bad blocks in emulator reset in predefined proportion
• add timebombs in predefined proportion excluding manufacturer bad blocks
• remove remnants of dhara error passing
• add functions returning erased/empty block status and marked bad block status
• remove remnants of dhare sector reading/writing

• random fatal failure to erase
• random non-fatal failure to erase (repeat recover)
• random non-fatal failure to erase (repeat does not recover)

• add erase, write and read count etc. to block descriptor
• remove structure with global emulator statistics
• implement function that populates global statistics iterating blocks

• genrate big table with ~15 Mb total size and record size ~48 byte
• generate big table approximately 1 Mb with records ~200 byte
• generate table with single record ~180 byte

Buffer for prepare data in memory for writing to a hole NAND erase block.
Writing to buffer must enforce 2-byte alignment.
Includes header for a block with a magic, identification of writing session, CRC32 and offset/size of written data.
CRC32 is calculated for data written, block header excluded.
Block is shuffled after writing.

• start new block buffer with incomplete header
• add small table
• add big table

1. calculate number of records that fit to available space in block
2. write table header
3. write data
4. commit block header
