sfxge: add prefast annotation to common code return types
Using a typedef for common code return types (rather than "int")
allows the Prefast static analyser to understand when a function
has been successful (and thus when its postconditions must hold).
This greatly reduces then number of false positives reported by
prefast for error paths in common code functions.

sfxge: modify nvram update functions for uio platform to support RFID-selectable presets
Dynamic config partitions on boards that support RFID are divided into
a number of segments, each formatted like a partition, with header,
trailer and end tags. The first segment is the current active
configuration.
The segments are initialised by manftest and each contain a different
configuration e.g. firmware variant. The firmware can be instructed
via RFID to copy a segment over the first segment, hence changing the
active configuration. This allows ops to change the configuration of
a board prior to shipment using RFID.
Changes to the dynamic config may need to be written to all segments (in
particular firmware versions written by manftest) or just the first
segment (changes to the active configuration). See SF-111324-SW.
If only the first segment is written the code still needs to be aware of
the possible presence of subsequent segments as writing to a segment may
cause its size to increase, which would overwrite the subsequent
segments and invalidate them.
Boards that do not support RFID will only have one segment in their
dynamic config partition.

Remove sv_prepsyscall, sv_sigsize and sv_sigtbl members of the struct
sysent.
sv_prepsyscall is unused.
sv_sigsize and sv_sigtbl translate signal number from the FreeBSD
namespace into the ABI domain. It is only utilized on i386 for iBCS2
binaries. The issue with this approach is that signals for iBCS2 were
delivered with the FreeBSD signal frame layout, which does not follow
iBCS2. The same note is true for any other potential user if
sv_sigtbl. In other words, if ABI needs signal number translation, it
really needs custom sv_sendsig method instead.
In vm_pageout_grow_cache(), do not re-try the inactive queue when
active queue scan initiated write.
Re-trying from the inactive queue when doing active scan makes the
loop never end if number of domains is greater than 1 and inactive or
active scan cannot reach the target.

- Add a kvm_native() routine that returns true if an open kvm descriptor

- Add a kvm_open2() function similar to kvm_openfiles(). It drops the
unused 'swapfile' argument and adds a new function pointer argument for
a symbol resolving function. Native kernels still use _fdnlist() from
libc to resolve symbols if a resolver function is not supplied, but cross
kernels require a resolver.

struct kvm_nlist instead of struct nlist.
- Add a kvm_read2() function similar to kvm_read() except that it uses
kvaddr_t instead of unsigned long for the kernel virtual address.
- Add a new kvm_arch switch of routines needed by a vmcore backend.
Each backend is responsible for implementing kvm_read2() for a given
vmcore format.
- Use libelf to read headers from ELF kernels and cores (except for
powerpc cores).
- Add internal helper routines for the common page offset hash table used
by the minidump backends.
- Port all of the existing kvm backends to implement a kvm_arch switch and
to be cross-friendly by using private constants instead of ones that
vary by platform (e.g. PAGE_SIZE). Static assertions are present when
a given backend is compiled natively to ensure the private constants
match the real ones.
- Enable all of the existing vmcore backends on all platforms. This means
that libkvm on any platform should be able to perform KVA translation
and read data from a vmcore of any platform.

Replace DPSRCS that work fine in SRCS.
This is so that 'make depend' is not a required build step in these
files.
DPSRCS is overall unneeded. DPSRCS already contains SRCS, so anything
which can safely be in SRCS should be. DPSRCS is mostly just a way to
generate files that should not be linked into the final PROG/LIB. For
headers and grammars it is safe for them to be in SRCS since they will
be excluded during linking and installation.
The only remaining uses of DPSRCS are for generating .c or .o files that
must be built before 'make depend' can run 'mkdep' on the SRCS c files
list. A semi-proper example is in tests/sys/kern/acct/Makefile where a
checked-in .c file has an #include on a generated .c file. The
generated .c file should not be linked into the final PROG though since
it is #include'd. The more proper way here is just to build/link it in
though without DPSRCS. Another example is in sys/modules/linux/Makefile
where a shell script runs to parse a DPSRCS .o file that should not be
linked into the module. Beyond those, the need for DPSRCS is largely
unneeded, redundant, and forces 'make depend' to be ran. Generally,
these Makefiles should avoid the need for DPSRCS and define proper
dependencies for their files as well.
An example of an improper usage and why this matters is in usr.bin/netstat.
nl_defs.h was only in DPSRCS and so was not generated during 'make all',
but only during 'make depend'. The files including it lacked proper
depenencies on it, which forced running 'make depend' to workaround that
bug. The 'make depend' target should mostly be used for incremental build
help, not to produce a working build. This specific example was broken in
the meta build until r287905 since it does not run 'make depend'.
The gnu/lib/libreadline/readline case is fine since bsd.lib.mk has 'OBJS:
SRCS:M*.h' when there is no .depend file.
