Add support for writing symbols and determining the assumed position of
binaries inside a mkimage image. This is useful as an example for other
entry types which might want to do the same thing.

This is needed to handle mkimage with inner section located itself in a
section.

Some boards don't use symbol writing but do access the symbols in SPL.
Provide an option to work around this.

Add the test which provides sequence of actions:
  1. create the image from binman dts
  2. create public and private keys
  3. add public key into dtb with fdt_add_pubkey
  4. 1. sign FIT container with new sign option with extracting from
        image
     2. sign exact FIT container with replacing of it in image
  5. check with fit_check_sign

Renumber test file from 277 to 280;
   Move UpdateSignatures() to Entry base class;
   Don't allow missing mkimage as it doesn't make sense;
   Propagate --toolpath for CI;
   Call mark_build_done() to avoid regenerating FIT:

Implement this feature since it is useful for updating FITs within an
image.

The patman directory has a number of modules which are used by other tools
in U-Boot. This makes it hard to package the tools using pypi since the
common files must be copied along with the tool that uses them.

To address this, move these files into a new u_boot_pylib library. This
can be packaged separately and listed as a dependency of each tool.

Add an entry flag called 'preserve' to indicate that an entry should be
preserved by firmware updates. Propagate this to FMAP too.

This property sets the minimum size of an entry, including padding but
not alignment. It can be used to reserve space for growth of an entry,
or to enforce a minimum offset for later entries in the section.
