existing libunwind used '0' in lsda_encoding as 'not present,'
whereas that is a valid encoding and does occur and would be
ignored. a missing encoding is actually 0xff.
The commit that addresses this is:

0 is a valid LSDA encoding and can be seen in statically linked
programs. Initialize lsdaEncoding to DW_EH_PE_omit and check for that
value to decide whether a value should be decoded.
more bugfixes are necessary. this update is up to:

Lazy VFP processing works a lot better if the functions contain a return
instruction.
replace invocations of -Ttext=.. with --section-start=.text=.. for
gnu gold-ld. it was giving very weird results when given page-rounded
values. --section-start=.text=.. works for both bfd-ld and gold.
-Add support for returning the amount of characters that would have been
written if the buffer was large enough.
-Protect code against NULL dereference.

The goal is to prevent a name collision with the expected mount/umount
function signatures, if we decide one day to allow any application
using those to work on MINIX.
At this moment the caller has to start the required services, but if we
implement that logic inside the mount/unmout function, this would allow
any application to call those function successfully.
By renaming those now, we prevent a possible ABI break in the future.

This cause in some software to assume we are linux, as this is rightly
only used there.
By default hide it behind _MINIX_SYSTEM, until we have removed traces
of it from getpeereid/[gs]etsocketopt and replaced it by the NetBSD
mechanism.

Currently we don't accept writable file mmap()s, as there is no
system in place to guarantee dirty buffers would make it back to
disk. But we can actually accept MAP_SHARED for PROT_READ mappings,
meaning the ranges aren't writable at all (and no private copy is
made as with MAP_PRIVATE), as it turns out a fairly large class of
usage.
. fail writable MAP_SHARED mappings at runtime
. reduces some minix-specific patches
. lets binutils gold build on minix without further patching

. define _MINIX_SYSTEM for all system code from minix.service.mk
. hide some system-level declarations and definitions
behind _MINIX_SYSTEM to cleanly fix host tool build problems on
Minix (such as: NONE being defined and paddr_t being used but not
declared)
. the similar definition _SYSTEM is unsuitable as it changes the
values of errno definitions

This fcntl requests all cached blocks associated with the minor device
number associated with the regular file are invalidated. If the file
is a block special, invalidate the blocks associated with that minor
device instead.
This is to be used for a test that tests unmapped file-mapped memory
ranges whose blocks are not in the cache and therefore must be fetched
from a FS.

- Fix for possible unset uid/gid in toproto
- Fix for default mtree style
- Update libelf
- Importing libexecinfo
- Resynchronize GCC, mpc, gmp, mpfr
- build.sh: Replace params with show-params.
This has been done as the make target has been renamed in the same
way, while a new target named params has been added. This new
target generates a file containing all the parameters, instead of
printing it on the console.
- Update test48 with new etc/services (Fix by Ben Gras <ben@minix3.org)
get getservbyport() out of the inner loop

This file was copied over to allow for the compilation of some
of the arch/i386 code, due to a bug in lib/libc/compat/Makefile.inc.
This patch fixes the situation, and removes the now useless header, as
well as remove a patch in lib/libc/stdlib/putenv.c

. rename kernel call specific signals fields to SYS_*
