tools: mkenvimage: Always consider non-regular files

At the moment mkenvimage has two separate read paths: One to read from
a potential pipe, while dynamically increasing the buffer size, and a
second one using mmap(2), using the input file's size. This is
problematic for two reasons:
- The "pipe" path will be chosen if the input filename is missing or
  "-".  Any named, but non-regular file will use the other path, which
  typically will cause mmap() to fail:
  $ mkenvimage -s 256 -o out <(echo "foo=bar")
- There is no reason to have *two* ways of reading a file, since the
  "pipe way" will always work, even for regular files.

Fix this (and simplify the code on the way) by always using the method
of dynamically resizing the buffer. The existing distinction between
the two cases will merely be used to use the open() syscall or not.

Andre Przywara [Sun, 30 Jun 2019 01:45:00 +0000 (02:45 +0100)]
tools: mkenvimage: Fix reading from slow pipe

It is perfectly fine for the read(2) syscall to return with less than
the requested number of bytes read (short read, see the "RETURN VALUE"
section of the man page). This typically happens with slow input
(keyboard, network) or with complex pipes.

So far mkenvimage expects the exact number of requested bytes to be
read, assuming an end-of-file condition otherwise. This wrong behaviour
can be easily shown with:
$ (echo "foo=bar"; sleep 1; echo "bar=baz") | mkenvimage -s 256 -o out -
The second line will be missing from the output.

Correct this by checking for any positive, non-zero return value.

This fixes a problem with a complex pipe in one of my scripts, where
the environment consist of two parts.

  (same concept can also be applied toother spl_XXX_load_image functions)

- Extend the FIT image loading function to allow skipping the parsing/
