d745c852be Mark MALLOC_DEFINEs static that have no corresponding MALLOC_DECLAREs.
This means that their use is restricted to a single C file.

7a0b13ed28 remove RESTARTABLE_PANICS option
This is done per request/suggestion from John Baldwin
who introduced the option.  Trying to resume normal
system operation after a panic is very unpredictable
and dangerous.  It will become even more dangerous
when we allow a thread in panic(9) to penetrate all
lock contexts.
I understand that the only purpose of this option was
for testing scenarios potentially resulting in panic.

d9bfecab53 Some netgraph parse types (such as for the 'value' field in ng_ksocket's
'struct ng_ksocket_sockopt') like to peek into the ng_mesg header for
information. Make sure when generating default values that we provide
a valid header to peek into.

b40ce4165d KSE Milestone 2
Note ALL MODULES MUST BE RECOMPILED
make the kernel aware that there are smaller units of scheduling than the
process. (but only allow one thread per process at this time).
This is functionally equivalent to teh previousl -current except
that there is a thread associated with each process.

Sorry john! (your next MFC will be a doosie!)

a514569e9a Fix a range checking bug in ng_int32_parse which affected 64-bit
machines.  The code formerly read:

    long val;
    if (val < (long)-0x80000000 || ...)
            return EINVAL;

The constant 0x80000000 has type unsigned int.  The unary `-'
operator does not change the type (or the value, in this case).
Therefore the promotion to long is done by 0-extension, giving
0x0000000080000000 instead of the desired 0xffffffff80000000.  I
got rid of the `-' and changed the cast to (int32_t) to give proper
sign-extension on all architectures and to better reflect the fact
that we are range-checking a 32-bit value.

This commit also makes the analogous changes to ng_int{8,16}_parse
for consistency.

27121ab1a4 Go back to using data_len in struct ngpppoe_init_data after discussions
with Julian and Archie.

Implement a new ``sizedstring'' parse type for dealing with field pairs
consisting of a uint16_t followed by a data field of that size, and use
this to deal with the data_len and data fields.

f8307e1233 Add two new generic control messages, NGM_ASCII2BINARY and
NGM_BINARY2ASCII, which convert control messages to ASCII and back.
This allows control messages to be sent and received in ASCII form
using ngctl(8), which makes ngctl a lot more useful.

This also allows all the type-specific debugging code in libnetgraph
to go away -- instead, we just ask the node itself to do the ASCII
translation for us.

Currently, all generic control messages are supported, as well as
messages associated with the following node types: async, cisco,
ksocket, and ppp.

See /usr/share/examples/netgraph/ngctl for an example of using this.

Also give ngctl(8) the ability to print out incoming data and
control messages at any time.  Eventually nghook(8) may be subsumed.

Several other misc. bug fixes.
