With the removal of unexec and purespace, the definitions in these files
are no longer used.  Remove them.

* src/firstfile.c:
* src/lastfile.c: Delete unused files.
* configure.ac (PRE_ALLOC_OBJ, POST_ALLOC_OBJ, FIRSTFILE_OBJ):
Remove variables and dependent code.
* msdos/autogen/Makefile.in:
* msdos/sed1v2.inp:
* src/Makefile.in: Don't use above deleted variables.
* src/deps.mk: Remove lastfile.c dependencies.

-/* How this works:
-
- Fdump_emacs dumps everything up to my_edata as text space (pure).
-
- The files of Emacs are written so as to have no initialized
- data that can ever need to be altered except at the first startup.
- This is so that those words can be dumped as shareable text.
-
- It is not possible to exercise such control over library files.
- So it is necessary to refrain from making their data areas shared.
- Therefore, this file is loaded following all the files of Emacs
- but before library files.
- As a result, the symbol my_edata indicates the point
- in data space between data coming from Emacs and data
- coming from libraries.
