Share Linux errno table with libsysdecode.
MFC r331056:2019-04-28T13:33:35ZDmitry Chagindchagin@FreeBSD.org2019-04-28T13:33:35Zurn:sha1:2a60be9efa962ad7d837fc12fb52d807c7962626
Share a single bsd-linux errno table across MD consumers
Three copies of the linuxulator linux_sysvec.c contained identical
BSD to Linux errno translation tables, and future work to support other
architectures will also use the same table. Move the table to a common
file to be used by all. Make it 'const int' to place it in .rodata.
(Some existing Linux architectures use MD errno values, but x86 and Arm
share the generic set.)
This change should introduce no functional change; a followup will add
missing errno values.
MFC r331057:
linux_errno.c: add newer errno values
Also introduce a static assert to ensure the list is kept up to date.

r314651:
sys/modules: normalize .CURDIR-relative paths to SRCTOP
This simplifies make output/logic
Tested with: `cd sys/modules; make ALL_MODULES=` on amd64
r318439:
Normalize .PATH on SRCTOP
This will help Jenkins dedupe 9 warnings between the static build and
the module build of ipsec(4).
Missed in SRCTOP conversion in r314651.

r318440:
Normalize SYSDIR on SRCTOP instead of .CURDIR
This is being done to simplify pathing for CFLAGS and source files.

Fix a copy/paste bug introduced during X86_64 Linuxulator work.
FreeBSD support NX bit on X86_64 processors out of the box, for i386 emulation
use READ_IMPLIES_EXEC flag, introduced in r302515.
While here move common part of mmap() and mprotect() code to the files in compat/linux
to reduce code dupcliation between Linuxulator's

Rework signal code to allow using it by other modules, like linprocfs:2015-05-24T17:47:20ZDmitry Chagindchagin@FreeBSD.org2015-05-24T17:47:20Zurn:sha1:4ab7403bbd76f466d482cd69035091c04e409c09
1. Linux sigset always 64 bit on all platforms. In order to move Linux
sigset code to the linux_common module define it as 64 bit int. Move
Linux sigset manipulation routines to the MI path.
2. Move Linux signal number definitions to the MI path. In general, they
are the same on all platforms except for a few signals.
3. Map Linux RT signals to the FreeBSD RT signals and hide signal conversion
tables to avoid conversion errors.
4. Emulate Linux SIGPWR signal via FreeBSD SIGRTMIN signal which is outside
of allowed on Linux signal numbers.

Refund the proc emuldata struct for future use. For now move flags from2015-05-24T15:54:58ZDmitry Chagindchagin@FreeBSD.org2015-05-24T15:54:58Zurn:sha1:bc273677607433dc32f6586c964a469f19867818
thread emuldata to proc emuldata as it was originally intended.
As we can have both 64 & 32 bit Linuxulator running any eventhandler
can be called twice for us. To prevent this move eventhandlers code
from linux_emul.c to the linux_common.ko module.

Introduce a new module linux_common.ko which is intended for the2015-05-24T15:51:18ZDmitry Chagindchagin@FreeBSD.org2015-05-24T15:51:18Zurn:sha1:67d39748499e85cff626c202aa2cb6e9f180283e
following primary purposes:
1. Remove the dependency of linsysfs and linprocfs modules from linux.ko,
which will be architecture specific on amd64.
2. Incorporate into linux_common.ko general code for platforms on which
we'll support two Linuxulator modules (for both instruction set - 32 & 64 bit).
3. Move malloc(9) declaration to linux_common.ko, to enable getting memory
usage statistics properly.
Currently linux_common.ko incorporates a code from linux_mib.c and linux_util.c
and linprocfs, linsysfs and linux kernel modules depend on linux_common.ko.
Temporarily remove dtrace garbage from linux_mib.c and linux_util.c
