The following types are nonstandard:
- u_char
- u_short
- u_int
- u_long
- u_int8_t
- u_int16_t
- u_int32_t
Replace them with the C99 standard types:
- uint8_t
- unsigned short
- unsigned int
- unsigned long
- uint8_t
- uint16_t
- uint32_t

None of these variables can actually be used before being initialized,
but unfortunately some old compilers are not smart enough to detect that.

Add a timestamp information for level 2 circuits, otherwise if the
circuit is marked as already processed on level 1 we will not process
level 2 areas.

Convert the list_delete(struct list *) function to use
struct list **. This is to allow the list pointer to be nulled.
I keep running into uses of this list_delete function where we
forget to set the returned pointer to NULL and attempt to use
it and then experience a crash, usually after the developer
has long since left the building.
Let's make the api explicit in it setting the list pointer
to null.
Cynical Prediction: This code will expose a attempt
to use the NULL'ed list pointer in some obscure bit
of code.

When we receive or generate new versions of fragments which are
curently pending for age out, we need to ensure that they are correctly
linked to their lsp0.

Standard IS-IS only supports up to 256 fragments per router. Recognize
when the information we want to advertise exceeds 256 fragments and
print a warning in this case instead of overflowing the fragment counter
and overwriting existing LSP fragments.

clang 5 is not widely available enough for people to indent with. This
is particularly problematic when rebasing/adjusting branches.

The FSF's address changed, and we had a mixture of comment styles for
the GPL file header. (The style with * at the beginning won out with
580 to 141 in existing files.)
Note: I've intentionally left intact other "variations" of the copyright
header, e.g. whether it says "Zebra", "Quagga", "FRR", or nothing.

The way thread.c is written, a caller who wishes to be able to cancel a
thread or avoid scheduling it twice must keep a reference to the thread.
Typically this is done with a long lived pointer whose value is checked
for null in order to know if the thread is currently scheduled. The
check-and-schedule idiom is so common that several wrapper macros in
thread.h existed solely to provide it.
This patch removes those macros and adds a new parameter to all
thread_add_* functions which is a pointer to the struct thread * to
store the result of a scheduling call. If the value passed is non-null,
the thread will only be scheduled if the value is null. This helps with
consistency.
A Coccinelle spatch has been used to transform code of the form:
if (t == NULL)
t = thread_add_* (...)
to the form
thread_add_* (..., &t)
The THREAD_ON macros have also been transformed to the underlying
thread.c calls.

- SPF is now per level only (no more per family)
- t_spf and pending removed from struct spftree and moved to
spf_timer field in struct isis_area
- show isis summary output changed to accomodate the per level SPF
- isis_spf_schedule6 and isis_run_spf6_lx functions are removed,
isis_run_spf_lx now calls isis_run_spf for both INET and INET6
- lsp related functions now call isis_spf_schedule only
I have a fix for 2 segmentation fault scenarios on the isis daemon:
1. When running a command "isis passive" on an interface in the
following context:
"end"
"configure terminal "
"interface dummy0"
"isis passive"
The trace back collected:
isis_adjacency.c:521
family=2,
root_sysid=0x20aee6d0 "", parent=0x20af4d68) at isis_spf.c:999

at isis_spf.c:1217
isis_spf.c:1372
isis_lsp.c:416
isis_lsp.c:1660
isis_main.c:368
The fix location:
file name: isisd/isis_adjacency.c
routine name: isis_adj_build_up_list
2. When deleting the existing isis router instance:
"end"
"configure terminal "
"no router isis DEAD"
The fix location:
isisd/isis_events.c, routine circuit_resign_level
isisd/isis_lsp.c, routine lsp_destroy
