Fixes for CVE-2018-16301, errors in pcapng reading.
PCAPNG reader applies some sanity checks before doing malloc().
- many optimisations improved: inter-procedural, profile-directed,
LTO, loops including user-controllable unroll support, and more.
- columns numbers added to line numbers in dwarf
- gcov extended significantly
- many sanitizer updates
- many new warning messages
- many better hints and more useful error messages
- minor ABI changes on x86-64 libstdc++, and some c++17 modes
- draft c++2a features
- better c++17 experimental support
- Armv8.4-A supported, better 8.2-A and 8.3-A support, including
32 bit arm port. cortex a-55, a-75 and a-55.a-75 combo support.
- in the GCC bugzilla, 8.1 shows 1149 bugs fixed, 8.2 shows 100, and
8.3 shows 158.
Solves kernel panic in NetBSD 8.1 amd64 on VirtualBox 6.0.12 r133076.
Triggered with an NVMe controller without any actual discs behind it:
nvme0 at pci0 dev 14 function 0: vendor 80ee product 4e56 (rev. 0x00)
nvme0: NVMe 1.2
nvme0: interrupting at ioapic0 pin 22

ld0: 0, 0 cyl, 16 head, 63 sec, 1 bytes/sect x 0 sectors
Code path is reached 4 times during normal boot, each time after wd0a
is already mounted; this patch avoids a crash with a dirty filesystem.
Storing struct ptrace_state information inside struct proc was vulnerable
to synchronization bugs, as multiple events emitted in the same time were
overwritting other ones.
Cache the original parent process id in p_oppid. Reusing here p_opptr is
in theory prone to slight race codition.
Change the semantics of PT_GET_PROCESS_STATE, reutning EINVAL for calls
prompting for the value in cases when there wasn't registered an
appropriate event.
Add an alternative approach to check the ptrace_state information, directly
from the siginfo_t value returned from PT_GET_SIGINFO. The original
PT_GET_PROCESS_STATE approach is kept for compat with older NetBSD and
OpenBSD. New code is recommended to keep using PT_GET_PROCESS_STATE.
Add a couple of compile-time asserts for assumptions in the code.
No functional change intended in existing ptrace(2) software.
All ATF ptrace(2) and ATF GDB tests pass.
This change improves reliability of the threading ptrace(2) code.
- pfil_run_hooks() can be called recursively, so we have to
#define FASTROUTE_RECURSION in fil.c
- ip6_if_output()/nd6_output() will free the mbuf on error, to make sure
to set *mpp to NULL so the caller won't try to free it again.
