* Apply relocations, jump tables are detected correctly now
* Use virtual files for patching and relocation targets
* Create continous sections where possible instead of a section per page
* Support for DOS extender bound LE executables
* Support page compression of type 1 (iterated) and 5 (compressed)
* Add support for 16 bit relocations
* Fix numerous issues, leaks, UB, etc
OpenBSD enables arm64 BTI or Intel IBT by default, except when the
binary was linked with -Wl,-z,nobtcfi in order to opt-out. In this case,
a PT_OPENBSD_NOBTCFI segment will exist, which we can indicate in the
bin info.

/wi was falling through the switch case and it was not accepting the
input correctly. Fix this by breaking at the end of the '/w' case so
that the search can begin.
rz_buf_read_at() with a negative addr on a ref (slice) buffer broke all
subsequent calls to rz_buf_read_at(). This is fixed by making sure to
always reset to the initial seek.
This bug was detected through xnu kernelcaches, where we may also skip
any obviously invalid read.
For bind chained fixups (pointing to imports parsed in the previous
commit) we reuse the patching code for classic relocs as the logic is
more generic here than for local chained fixups.
The LC_DYLD_CHAINED_FIXUPS load command references a new kind of imports
table that is used for binding chained fixups. A similar table may be
reconstructed from the legacy BIND_OPCODE_THREADED info. We now display
these new imports in `ii` instead of the classic undefined symbols and
use them to assign names to relocs.
Objective-C superclass resolution for chained fixups is also changed to
first check for relocs and then for a non-zero address read from memory
instead of ignoring relocs entirely when there is a non-zero value in
memory (this did not work for chained fixups as those already have
non-zero values before patching).
Chained fixups are essentially a new kind of relocs, so it makes sense
to also represent them as RzBinRelocs. Currently the results are
sometimes less meaningful than the reloc info that was parsed before
from indirectsyms in such cases, as chained imports are not parsed yet
and thus the target symbols of bind relocs are not yet known, hence the
temporarily BROKEN tests.
Some identical code from both mach-o 32 and 64 has been moved to
mach0_common.c to avoid duplicate compilation.
rz_mach0_platform_to_string() now recognizes all known platforms and the
information is shown as the subsys in the i command.
The "os" value was previously unreliably and ios sometimes showed as
"ios" and sometimes as "darwin" depending on the binary. Now the os is
"darwin" for all platforms. ios-* syscall files have thus been removed
as only darwin-* ones will be used.
