Implement proposal #54880, to automatically seed the global source.
The justification for this not being a breaking change is that any
use of the global source in a package's init function or exported API
clearly must be valid - that is, if a package changes how much
randomness it consumes at init time or in an exported API, that
clearly isn't the kind of breaking change that requires issuing a v2
of that package. That kind of per-package change in the position
of the global source is indistinguishable from seeding the global
source differently. So if the per-package change is valid, so is auto-seeding.
And then, of course, auto-seeding means that packages will be
far less likely to depend on the specific results of the global source
and therefore not break when those kinds of per-package changes
happen in the future.
Seed(1) can be called in programs that need the old sequence from
the global source and want to restore the old behavior.
Of course, those programs will still be broken by the per-package
changes just described, and it would be better for them to allocate
local sources rather than continue to use the global one.
Fixes#54880.

Notably, the older versions of git do not support:
- 'git branch -m' before the current branch has a commit
- 'init.defaultBranch' in the '.gitconfig' file, and
- 'git branch -c'.
We address those by, respectively:
- waiting to run 'git branch -m' until after the first commit
- always running 'git branch -m' explicitly to set the branch name, and
- using 'git checkout' instead of 'git branch -c' to set branch parents.

This change decouples the script engine from both cmd/go and the
testing package; I intend to reuse it in the replacement for the
vcs-test.golang.org server.
This change also adds a few new script commands:
- 'echo' echoes its arguments, useful for verifying argument expansion.
- 'cat' prints the contents of files, useful for debugging failing script tests.
- 'help' displays information about script commands and conditions,
reducing the toil of maintaining lists in the README file.
The 'cmp' and 'cmpenv' commands now use internal/diff instead of their
own separate diff implementation.
The 'env' command now writes to the script log instead of the stdout
buffer. (This makes it more consistent with the behavior of other
synchronous builtins.)
The 'stale' command no longer logs output when a target is
unexpectedly non-stale. (However, the ouput of the 'stale' command is
not usually very useful anyway.)
The 'grep', 'stdout', and 'stderr' commands now display matching lines
(like Unix 'grep'), making their negation behavior more consistent
with running real commands on a command-line.
Likewise, the 'cmp' command now always displays differences. That
makes it useful with the '?' prefix to produce diffs for informational
purposes while debugging.

This patch has a couple of minor fixes to new-style counter insertion
(noticed these problems while working on the fix for issue 56370).
First, make sure that the function registration sequence (writing of
nctrs, pkgid, funcid to counter var prolog) comes prior to the first
counter update (they were reversed up to this point, due to an
artifact of the way cmd/internal/edit operates).
Second, fix up "per function" counter insertion mode (an experimental
feature disabled by default that adds just a single counter to each
function as opposed to one per basic block), which was failing to
insert the single counter in the right place.

coverage counter function registration sequence. The scenario is that
package P contains a function F that is built with coverage, then F is
inlined into some other package that isn't being instrumented. Within
F's exported function body counter updates were being done with
atomics, but the initial registration sequence was not, which had the
potential to trigger a race. Fix: if race mode is enabled and we're
using atomics for counter increments, also use atomics in the
registration sequence.
