2e0829fb5a Made lwip timeout measurements accurate by no longer returning 1 millisecond
whenever sys_arch_mbox_wait() and sys_arch_sem_wait() get a message or
semaphore immediately. Updated documentation for this change.

32d9f25a6f Fixed up and made work a PBUF_REF type. Most of the code uses this now
instead of PBUF_ROM. This addition allows support of copy-on-demand where the
lower layers can call pbuf_unref() which tests for any PBUF_REF buffers and
replaces them with PBUF_POOL buffers. This is now used
everywhere. pbuf_unref() is called in ARP queueing and in the coldfire
driver, which puts frames on a DMA queue and frees them later.

Along with this change pbuf_free() now goes through the entire chain of
buffers and tests all the ref counters, not just the first one. Generally now
pbuf_ref_chain() should be called and not pbuf_ref(). This change was made
because it is possible for the head of the pbuf chain to have a different
count than the payload pbuf which might have been passed by the application.

7f1becc682 Allow minimal unix target to build in cygwin (but not necessarily run).
Applied a patch from Marc Boucher which has the following changes:

1) Fixed sys_arch.txt documentation to have new return type from
   sys_thread_new.

2) Removed unnecessary casts on calling sys_timeout() in certain files.

3) Removed some unnecessary break statements after return statements.

4) Changed sys_timeout_remove() to sys_untimeout().

5) Added some forgotten #ifndef SYS_LIGHTWEIGHT_PROT to memp.c

6) Changed LWIP_DIAG and LWIP_PLATFORM_ASSERT to have do while().

dd2fa15e8a Add the following features and bugfixes:
Added select() functionality to sockets library.
Support for errno in sockets library.
Byte ordering fixes.
basic lwip_ioctl(), FIONREAD, get/setsockopt() etc. support

- added additional argument to netif_add to pass state pointer so that the
if_init function has access to context information before
the interface is added, without accessing globals.

- added netif_remove()

- to conserve cpu load the tcpip_tcp_timer should only be active
when tcbs that need it exist.

- pass length of available data to callbacks for NETCONN_EVT_RCV events

- added tcpip_link_input(), a hack to allow processing of PPP
packets in tcpip_thread() context. This saves threads and context
switches.

- renamed incompatible ASSERT() macro to LWIP_ASSERT() to avoid name
collision.

- changed a bunch of %d's to %u's in format strings for unsigned values.

- added ip_frag to lwip_stats.

- changed IP_REASS_MAXAGE and IP_REASS_TMO defaults to more realistic
values.

- added sys_timeout_remove() function to cancel timeouts (needed by PPP
amongst other things).

- tolerate NULL returns from sys_arch_timeouts() since some threads might
not need to use or have timeouts.

- added sys_sem_wait_timeout()

- moved mem_malloc() function to end of mem.c to work around tasking
compiler bug.

- automatically bind to local tcp port if 0.

- allow customization of port ranges for automatic local bindings.

- corrected various typos, spelling errors, etc..

Thanks to Marc Boucher for many of these changes.

98fbb855fb Added lightweight protection. In coldfire this is implemented by disabling
interrupts. In unixsim this is implemented by using a mutex. Uses #define
SYS_LIGHTWEIGHT_PROT to enable. It is enabled in coldfire by default, but
disabled in unixsim.

Fixes bug 2005 if you enable SYS_LIGHTWEIGHT_PROT. So the bug is closed.
