Done with a combination of regex'ing and banging my head against a wall.

This patch allows to store Link State Information received through the various
LSAs into a dedicated Traffic Engineering Database (TED). This feature is
automatically activated once mpls-te is enabled.
A new CLI command `mpls-te export` permits to export the TED to other daemons
through the new ZAPI Opaque Link State messages. In complement, a new CLI
command `show ip ospf mpls-te database ...` output the contains of the TED to
the console.
Major modifications take place in ospf_te.[c, h]. File ospf_zebra.c has been
modified to handle TED synchronisation request.

This patch corrects two problems that affect Inter-AS LSA:
1/ Inter-LSA are never flood due to an incorrect setting of specific flag.
2/ When looking to the detail of the OSPF LSA with the command
`show ip ospf database opaque-xxx`, it appears that only the Inter-AS
advertising router is abble to show the detail of the Inter-AS LSA. Foreign
routers are only abble to show the header of this Inster-AS LSA. The problem
comes from the registration of Inter-AS management functions which is done
only on the advetising router. So, the function `ospf_mpls_te_show_info()` is
never call on neighbor routers that have not resgistered Inter-AS management
callback functions.
First, this patch modify functions `set_linkparams_inter_as()` and
`unset_linkparams_inter_as()` to respectively set and unset flags that control
the Inter-AS LSA flooding. Flag & Type from `struct mpls_te_link` have been
redefined: Flag is used to determine if flooding is AS or not and Type is only
used to determine the type of the LSA.
Second, this patch register Inter-AS management functions for both AS and Area
flooding with a different function for LSA origination as parameter is passed
as void and it is mandatory to determine the flooding context:
`struct *ospf` for AS flooding and `struct *ospf_area` for Area flooding.

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

When preforming CI test, CLI command 'no router ospf' followed by a
'router ospf' is performed to clean up the previous configuration.
Ospfd crash when configuring 'netwoark area'.
This is due to opsf_opaque_term() introduce in previous commit that cause this
crash. It remove not only Opaque LSA but also the list through the call to
'list_delete_and_null()' function. Same take place in 'ospf_mpls_te_term()',
'ospf_router_info_term()' and 'ospf_ext_term()' function.
New set of 'ospf_XXX_finish()' has been introduced to solve this issue while
keeping the possiblity to terminate properly the Opaque LSA and remove MPLS
LFIB entries set by Segment Routing.

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.

NOTE: I am squashing several commits together because they
do not independently compile and we need this ability to
do any type of sane testing on the patches. Since this
series builds together I am doing this. -DBS
This new structure is the basis to get new link parameters for
Traffic Engineering from Zebra/interface layer to OSPFD and ISISD
for the support of Traffic Engineering
* lib/if.[c,h]: link parameters struture and get/set functions
* lib/command.[c,h]: creation of a new link-node
* lib/zclient.[c,h]: modification to the ZBUS message to convey the
link parameters structure
* lib/zebra.h: New ZBUS message

Add support for IEEE 754 format
* lib/stream.[c,h]: Add stream_get{f,d} and stream_put{f,d}) demux and muxers to
safely convert between big-endian IEEE-754 single and double binary
format, as used in IETF RFCs, and C99. Implementation depends on host
using __STDC_IEC_559__, which should be everything we care about. Should
correctly error out otherwise.
* lib/network.[c,h]: Add ntohf and htonf converter
* lib/memtypes.c: Add new memeory type for Traffic Engineering support

Since LEGAL_TE_INSTANCE_RANGE() was being passed an unsigned int, a warning
was being thrown due to the compare against >= 0. Since this macro was used
only in one place, I removed the macro for an explict compare against a
constant for the MAX.
