This change makes the direct call darwin loadSystemRoots implementation
match the existing cgo implementation, which in turn _mostly_ matches
the Apple implementation. The main change here is that when
SecTrustSettingsCopyTrustSettings the error is ignored, and can either
cause a fallback to check admin trust settings, or cause the
certificate to be marked kSecTrustSettingsResultUnspecified.
As well as updating the implementation to match the cgo one, this
change also updates the documentation of how the fallbacks work and
how they match the Apple implementations. References are made to the
Apple source where appropriate. This change does not update the
existing comments in the cgo implementation, since the goal is to
delete that code once the direct call implementation is matured.

Currently, for symbols defined in other packages and referenced
by index, we don't record its name in the object file, as the
linker doesn't need the name, only the index. As a consequence,
tools like objdump and nm also don't know the referenced symbol
names and cannot dump it properly.
This CL adds referenced symbol names to the object file. So the
object file is self-contained. And tools can retrieve referenced
symbol names properly.
Tools now should work as good for new object files as for old
object files.

This reverts CL 229246.
For new indexed object files, in CL 229246 we added symbol index
to tools (nm, objdump) output. This affects external tools that
parse those outputs. And the added index doesn't look very nice.
In this release we take it out. For future releases we may
introduce a flag to tools (nm, objdump) and optionally dump the
symbol index.
For refererenced (not defined) indexed symbols, currently the
symbol is still referenced only by index, not by name. The next
CL will make the object file self-contained, so tools can dump
the symbol names properly (as before).

During DWARF line table emission in the linker, prior to issuing a
DW_LNE_end_sequence op to mark the end of the line table for a
compilation unit, advance the PC to produce an address beyond the last
text address in the unit (this is required by the DWARF standard).
Because of the way that GDB interprets end-sequence ops, we were
effectively losing the last row in the line table for each unit, which
degraded the debugging experience.
This problem has been around for a while, but has surfaced recently
due to changes in line table generation. Prior to Go 1.14, the DWARF
line table was emitted entirely in the linker, and a single monolithic
line table was created for each Go package (including functions from
assembly). In 1.14 we moved to having the compiler emit line table
fragments for each function, and having the linker stitch together the
fragments. As part of this change we moved to a model in which each
"go tool compile/asm" output has its own DWARF line table instance,
meaning that there are many more "end sequence" ops, which made the
problem more visible.
Fixes#38192.

Previously we did not steal timers from running P's, because that P
should be responsible for running its own timers. However, if the P
is running a CPU-bound G, this can cause measurable delays in running
ready timers. Also, in CL 214185 we avoided taking the timer lock of a P
with no ready timers, which reduces the chances of timer lock contention.
So, if we can't find any ready timers on sleeping P's, try stealing
them from running P's.
