Since elftoolchain's cxxfilt is rather far behind on features, and we

It supports the same options as elftoolchain cxxfilt, though it doesn't
have support for old ARM (C++ Annotated Reference Manual, not the CPU)
and GNU v2 manglings. But these are irrelevant in 2020.
Note: as we already compile the required libraries as part of libllvm,
this will not add any significant build time either.

The previous behavior was to support nested #ifdef and #ifndef, but to
return to unconditional parsing after the next #endif, independently of
the number of previously parsed conditions.
E.g. after "#ifdef A / #ifdef B / #endif" the following lines were
unconditially parsed again, independently of A and/or B being defined.
The new behavior is to count the level of false conditions and to only
restart parsing of calendar entries when the corresponding number of
#endif tokens have been seen.
In addition to the above, an #else directive has been added, to toggle
between parsing and ignoring of the following lines.
No validation of the correct use of the condition directives is made.
#endif without prior #define or #ifndef is ignored and #else toggles
between parsing and skipping of entries.
The MFC period has been set to 1 month to allow for a review of the
changes and for a discussion, whether these modifications should not
be merged at all.
No correct input file is parsed differently than before, but if calendar

Literal references to /usr/local exist in a large number of files in
the FreeBSD base system. Many are in contributed software, in configuration

source files or headers outside the contrib and sys/contrib directories.
This commit makes it possible to set _PATH_LOCALBASE in paths.h to use
a different prefix for locally installed software.
In order to avoid changes to openssh source files, LOCALBASE is passed to
the build via Makefiles under src/secure. While _PATH_LOCALBASE could have
been used here, there is precedent in the construction of the path used to
a xauth program which depends on the LOCALBASE value passed on the compiler
command line to select a non-default directory.
This could be changed in a later commit to make the openssh build
consistently use _PATH_LOCALBASE. It is considered out-of-scope for this

In fact, multiple ports could exist (e.g. per locale) without conflicting

Calendar files in LOCALBASE override similarily named ones in the base
system. This could easily be changed if the base system calendars should
have precedence, but it could lead to a violation of POLA since then the
port's files were ignored unless those in base have been deleted.

According to git blame the trymmap() function was added in 1996 to skip
mmap() calls for NFS file systems. However, nowadays mmap() should be
perfectly safe even on NFS. Importantly, onl ufs and cd9660 file systems
were whitelisted so we don't use mmap() on ZFS. It also prevents the use
of mmap() when bootstrapping from macOS/Linux since on those systems the
trymmap() function was always returning zero due to the missing MFSNAMELEN
define.
This change keeps the trymmap() function but changes it to check whether
using mmap() can reduce the number of system calls that are required.
Using mmap() only reduces the number of system calls if we need multiple read()
syscalls, i.e. if the file size is > MAXBSIZE. However, mmap() is more expensive
than read() so this sets the threshold at 4 fewer syscalls. Additionally, for
larger file size mmap() can significantly increase the number of page faults,
so avoid it in that case.
It's unclear whether using mmap() is ever faster than a read with an appropriate
buffer size, but this change at least removes two unnecessary system calls
for every file that is installed.

This change is based on the nexthop objects landed in D24232.
The change introduces the concept of nexthop groups.
Each group contains the collection of nexthops with their
relative weights and a dataplane-optimized structure to enable
efficient nexthop selection.
Simular to the nexthops, nexthop groups are immutable. Dataplane part
gets compiled during group creation and is basically an array of
nexthop pointers, compiled w.r.t their weights.
With this change, `rt_nhop` field of `struct rtentry` contains either
nexthop or nexthop group. They are distinguished by the presense of
NHF_MULTIPATH flag.
All dataplane lookup functions returns pointer to the nexthop object,
leaving nexhop groups details inside routing subsystem.
User-visible changes:
The change is intended to be backward-compatible: all non-mpath operations
should work as before with ROUTE_MPATH and net.route.multipath=1.
All routes now comes with weight, default weight is 1, maximum is 2^24-1.
Current maximum multipath group width is statically set to 64.
This will become sysctl-tunable in the followup changes.
Using functionality:
* Recompile kernel with ROUTE_MPATH
* set net.route.multipath to 1
route add -6 2001:db8::/32 2001:db8::2 -weight 10
route add -6 2001:db8::/32 2001:db8::3 -weight 20
