[U-Boot] [PATCH v2 15/31] binman: Allow entries to expand after packing

[sjg at google.com]

Add support for detecting entries that change size after they have already
been packed, and re-running packing when it happens.

This removes the limitation that entry size cannot change after
PackEntries() is called.

Changes in v2:
- Avoid dual assignment in ResetForPack()
- Show a message when a section's size changes
- Use 3 packing passes instead of two, and add a comment
- Use bytearray for Python 3
