Limit the maximum nesting depth when parsing to protect against stack
overflow, permitted by https://tools.ietf.org/html/rfc7159#section-9
A nesting depth limit of 10,000 was chosen to be a conservative
balance between avoiding stack overflow and avoiding impacting
legitimate JSON documents.
10,000 is less than 1% of the experimental stack depth limit
with the default stack size:
* On 64-bit systems, the default stack limit is 1GB,
which allows ~2,800,000 frames of recursive parsing
* On 32-bit systems, the default stack limit is 250MB,
which allows ~1,100,000 frames of recursive parsing

Always shadow or modify the original parameter name. With code like:
func index(item reflect.Value, ... {

It was possible to incorrectly use 'item' and 'v' later in the function,
which could result in subtle bugs. This is precisely the kind of mistake
that led to #36199.
Instead, don't keep both the old and new reflect.Value variables in
scope. Always shadow or modify the original variable.
While at it, simplify the signature of 'length', to receive a
reflect.Value directly and save a few redundant lines.

When internal linking PIE, R_ADDR relocations cannot be resolved
statically so we generate dynamic relocations for it. We don't
apply the relocations statically, so the bytes in the file are
left unset (likely zero). This makes some tool that examines the
file statically, e.g. go version, to fail to find the referenced
addresses.
This CL makes the linker also apply the relocations to the file
content, so it holds the correct offsets and so can be examined
statically.

Go's PIE binaries have tons of relocations, all R_X86_64_64 [1] when
internally linked. R_X86_64_64 relocations require symbol lookup in the
dynamic linker, which can be quite slow. The simple Go HTTP server
in #36028 takes over 1s to complete dynamic linking!
The external linker generates R_X86_64_RELATIVE [2] relocations, which
are significantly more efficient. It turns out that generating these
relocations internally is quite simple, so lets do it.
Rather than referencing targ.Dynid in r_info and having the dynamic
linker do a symbol lookup and then add (final targ address) + r.Add, use
AddAddrPlus to generate another R_ADDR to have the linker compute (targ
address + r.Add). The dynamic linker is then only left with base address
+ r_addend.
Since we don't reference the symbol in the final relocation, Adddynsym
is no longer necessary, saving ~1MB (of ~9MB) from the binary size of
the example in #36028.

import graph is not always acyclic. (The package import graph must be
acyclic given a specific set of build tags, but the 'mod' subcommands
intentionally ignore build tags.)
I'm not sure whether we have any existing regression tests that cover
this sort of cycle, so I'm adding one now. Thankfully, it passes!
