063e4950f4 Added support for configuring base filesystem. First attempt at 
a full mount table at initialization.  This is the wrong place
to mount filesystems 2-n since no device drivers are initialized
yet.

5d36b344ae Fixed bug which resulted in misaligned object control structures 
being allocated.  This bug manifested itself on the SPARC
since it uses ldd/std in its context save/restore routines.

32441ab768 Added a comment to indicate that if a task blocked on a priority 
based thread queue were to be reinserted based on its new priority,
this is where the logic would go.

c1cdaa0ce8 Patch from Emmanuel Raguet <raguet@crf.canon.fr> and Eric Valette 
<valette@crf.canon.fr> to add a port of the GoAhead web server
(httpd) to the RTEMS build tree.  They have successfully used
this BSP on i386/pc386 and PowerPC/mcp750.

Mark and Joel spoke with Nick Berliner <nickb@goahead.com> on
26 Oct 1999 about this port and got verbal approval to include
it in RTEMS distributions.

657e1bf66b Added initial cut at miniIMFS which leaves out memfile and directory 
readdir support.  The next step is to add a mount table and configure
either the miniIMFS or the full IMFS at the application level.

8379ada798 Patch from Eric Norum <eric@cls.usask.ca> to address the following problem 
report from Philip A. Prindeville <philipp@zembu.com>:

        I was working on a device driver for a certain ethernet chipset that
    occassionally wraps in its buffer, and causes a resulting mbuf chain
    with only a few dozen bytes in the first mbuf of the chain.

        I wouldn't have thought this would be a problem, until I ran some
    stress tests that flooded the ethernet receiver with packets and
    started to get panics here:

       250
       251          if (m->m_pkthdr.len < sizeof(struct ip))
       252                  goto tooshort;
       253
       254  #ifdef  DIAGNOSTIC
       255          if (m->m_len < sizeof(struct ip))
       256                  panic("ipintr mbuf too short");
       257  #endif
       258
       259          if (m->m_len < sizeof (struct ip) &&
       260              (m = m_pullup(m, sizeof (struct ip))) == 0) {
       261                  ipstat.ips_toosmall++;
       262                  return;
       263          }
       264          ip = mtod(m, struct ip *);

    and the panic was at line 256.  But if I #undef'd DIAGNOSTICS,
    then the m_pullup() at line 260 does the right thing and the packet
    ends up being processed just fine.

    So I started wondering, (a) why was the test checking for
    something that apparently wasn't a fatal condition but rather
    one that is subsequently recovered from a couple of lines later
    and (b) why panic as a diagnostic "aid" from a recoverable
    condition rather than just (say) log a message to the console?

    All of this seems overly severe for no reason that is readily
    apparent to me.
