bump mac dep (#1957)

0.1.47

stage2, uefi: allocate untyped buffers from tagged region

This addresses a long-standing bug in targets that use a rewind tag for
values (specifically the stage2 and uefi bootloaders), whereby an untyped
buffer allocation was being allocated without creating space for the tag
type. This could manifest in an incorrect tag type being read for a buffer. To
remedy this, an additional tagged region heap is created of type tag_unknown,
and untyped buffer values (currently only coming from decode_value() when
using an old TFS encoding for backward compatibility) are allocated from that
heap.

0.1.46

getsockopt(): add support for SO_DOMAIN

This socket option at the SOL_SOCKET level contains the socket
domain value (e.g. AF_INET or AF_INET6).

0.1.45

netlink RTM_GETADDR: add support for AF_INET6 and AF_UNSPEC

This adds netlink support for reporting IPv6 interface addresses via the
RTM_GETADDR request. It also handles the AF_UNSPEC address family by reporting
both IPv4 and IPv6 addresses.

0.1.44

ATA: honor maximum number of sectors in each I/O request

This commit adds a new function to the ATA disk driver to retrieve
the maxiumum number of sectors that can be submitted in a single
I/O request, which depends on whether LBA48 addressing is
supported. This new function is called by both the x86_64
bootloader and the kernel ATA PCI driver, which check the maximum
sector count value to split each I/O request so that it doesn't
exceed the limit.
This fixes booting on vsphere VMs with IDE disk emulation.
