[Elftoolchain-developers] Support for "in-place" updates to ELF objects has been added to libelf

[Joseph K. <jk...@us...>]

After changeset [1712], libelf supports "in-place" updation of ELF
objects opened in ELF_C_RDWR mode.

This feature required a number of changes to the implementation of
`elf_update()`.  While I have added a number of test cases to the
libelf test suite to verify that libelf continues to work as expected,
there could still be bugs lurking in the code.

Please do let me know if you notice any regressions, or if you have
suggestions for additional test coverage.

Thanks,
Koshy
