sim_imd: Check for EOF when reading IMD track headers

The recent change to check that the IMD file track header record is 5
bytes introduced a problem with the end-of-file triggering an open file
error - instead of the previous behaviour where the number of bytes in
the track header was ignored and end-of-file was checked.

I noticed this after fetching and compiling the latest simh altairz80 - it
was refusing to my mount floppy disk IMD image files (which I had made
from 8-inch floppies back in 2006).

/Users/tony/s100/cpm3bk.ini-58> att disk1a0 /Users/tony/s100/C3BKSIMH.IMD
File open error
```

Looking at the commit history, I saw the change by Howard Harte to
sim_imd.c to "Resolve CID 15024481502460" - presumably to fix the
call to sim_fread() that was not checking the returned result.
Howard's "fix" broke the parsing of the IMD file sector headers by
not checking for an end-of-file condition (at the end of file it
would read 0 bytes and this was now treated as a fatal error - whereas
the old code had a check for end-of-file after the call to sim_fread()).

This commit now detects end-of-file correctly, as well as verifying
the track header is 5 bytes.

6 months agodoc: Revise the SIMH User's guide to describe startup config files executed

doc: Revise the SIMH User's guide to describe startup config files executed

The key change is the addition of:

When a simulator starts execution, the following sequence of simh command
files are executed if they are found:
    1. If a file named simh.ini is located in your HOME directory, it is
        executed.
    2. If the simh.ini file in your HOME directory isn’t found, a file named
        simh.ini in your current working directory is executed if it exists.
    3. If the simulator is invoked with any arguments, then the arguments are
        presumed to be a command file and possible arguments to that command
        file which is executed.
    4. If the simulator is invoked without any arguments, then a command file
        with the same name as the simulator binary with .ini appended that is
        located in the current working directory is executed.

Note, that up to 2 separate command files may be executed on simulator
startup.  The simh.ini file allows the user to define local user
preferences that align with their personal goals for simulator execution
across all simulators that may be used on their system.

Steps 3 and 4 were inherited from simh v3.x.  Steps 1 and 2 was inspired
by conversations with J. David Bryan in April of 2012.  Some how it
never got documented.
