Insert padding in __cxa_exception struct for compatibility
Similar to https://github.com/llvm/llvm-project/commit/f2a436058fcb, the
addition of __attribute__((__aligned__)) to _Unwind_Exception (in commit
b9616964) causes implicit padding to be inserted before the unwindHeader
field in __cxa_exception.
Applications attempt to get at the earlier fields in __cxa_exception, so
preserve the same negative offsets in __cxa_exception, by moving the
padding to the beginning of the struct.
The assumption here is that if the ABI is not aware of the padding
before unwindHeader and put the referenceCount/primaryException in
there, no padding should exist before unwindHeader.
This should make libreoffice's custom exception handling mechanisms work
correctly, even if it was built against an older cxxabi.h/unwind.h pair.

hostapd calls pcap_next(3) to read the next packet off the wlan interface.
pcap_next() returns a pointer to the packet header but does not indicate
success or failure. Unfortunately this results in an infinite loop (100%
CPU) when the wlan device disappears, i.e. when a USB wlan device is
manually removed or a USB error results in the device removal. However
pcap_next_ex(3) does return success or failure. To resolve this we use
pcap_next_ex(), forcing hostapd to exit when the error is encountered.
An error message is printed to syslog or stderr when debugging (-d flag)
is enabled. Unfortunately wpa_printf() only works when debugging is enabled.

This register set contains the values of the fsbase and gsbase
registers. Note that these registers can already be controlled
individually via ptrace(2) via MD operations, so the main reason for
adding this is to include these register values in core dumps. In
particular, this will enable looking up the value of TLS variables
from core dumps in gdb.
The value of NT_X86_SEGBASES was chosen to match the value of
NT_386_TLS on Linux. The notes serve similar purposes, but FreeBSD
will never dump a note equivalent to NT_386_TLS (which dumps a single
segment descriptor rather than a pair of addresses) and picking a
currently-unused value in the NT_X86_* range could result in a future
conflict.

[DebugInfo] Correctly handle arrays with 0-width elements in GEP salvaging
Fixes an issue where GEP salvaging did not properly account for GEP
instructions which stepped over array elements of width 0 (effectively a
no-op). This unnecessarily produced long expressions by appending
`... + (x * 0)` and potentially extended the number of SSA values used
in the dbg.value. This also erroneously triggered an assert in the
salvage function that the element width would be strictly positive.
These issues are resolved by simply ignoring these useless operands.
