f8f75cef5b BSS is now zeroed by libprefix (along with the otherwise non-zeroable 
portions such as the stack) during the installation process.

init_fns() are called from main().  We need to think about initial
control flow some more.

10c28a51bd Create two easy-to-use entry points in libprefix: install and 
install_prealloc.  I *think* these will suffice for all the 16-bit
prefixes.

9e1dd6402d <name>_size variable is no longer needed, since we don't copy the code. 
However, it's worth adding a .size directive so that objdump reports the
correct sizes for the code fragments.

9fcded3d23 Towards a(nother) new real-mode infrastructure, in which we take 
advantage of the fact that we have to have a permanently-resident block
in base memory.

8f62b39c03 Move stack out to separate object, so that having a stack doesn't drag in 
setup.S.

d081d65d48 This should be much more elegant: we use flat real mode for the 
highmem data, so decompress16 will be able to unpack blocks bigger
than 64kB.

cc8821a443 Checking in because I don't want to lose this rather neat code for 
running the decompresser in 16:16 protected mode using the real-mode
stack.  However, there's an even simpler way to do it...

04b6a1e004 Make all TCP methods optional; at least FTP data is a read-only 
connection and so legitimately ignores acked() and senddata().

bac97eb979 Change semantics of network API so that packet-absorbing calls *always* 
take ownership of the packet, rather than doing so only if they return
success.  This breaks semantic compatibility with Linux's
hard_start_xmit() method, but means that we don't have to worry so much
about error cases.

Split mechanism of processing received packets (net_rx_process()) out
from policy (net_step()), preparatory to putting net_step() in a separate
object.

23c494d14e Added basic code for implementing co-operative multitasking. 
Yes, you really can do it in 65 bytes.

d8e99bf28f Gave up on adding POSIX errno's as required, and just added (almost) all 
of them in one go.

EBADIMG has been replaced by ENOEXEC, and EIMGRET by ECANCELED.

95f8a42930 Removed incorrect comment; malloc() is inefficient only when the 
alignment and size are both powers of two, and there's no way to
specify an alignment through the malloc() interface anyway.

b601a7d355 Updated memory allocator to improve support for unaligned or partially 
aligned blocks.

Moved header to include/malloc.h, since we now also provide the
POSIX-like malloc()/free() pair.

Not yet tested.

2f0d412210 Add __constant_flsl(), because it's useful for finding out the next 
power-of-two up from a given constant via
  ( 1 << fls ( constant - 1 ) )

fls(), flsl(), ffs() and ffsl() appear in strings.h according to
POSIX.
