4127a6c056 main_edit.c: get rid of malloc warning 
A warning was present when building RTEMS that stated that the argument
for malloc() exceeded the maximum object size. To get rid of this, I
  changed many places where 'int' was being used to 'size_t'.

1dbd1079a5 shell/main_edit.c: Fix string truncation warning 
Using strlcpy() instead of strncpy():

1) Prevents the compiler warnings
2) Ensures, the string is NUL terminated.
3) Avoids that strncpy() unnecessary fills the unused part of the buffer with
   0 bytes.

(Note that realpath() also returns NULL if the file does not exist - that
happens always if someone creates a new file with the editor of the shell.)

42c77e9982 shell: Add an editor to the shell. 
This is a small (21K on sparc) editor that provides some powerful
features useful when a file needs editing on an embedded
board. No need to copy files off, edit, copy back.
