To give ample warning for users wishing to override Git's the fall-back
for an unconfigured `init.defaultBranch` (in case we decide to change it
in a future Git version), let's introduce some advice that is shown upon
`git init` when that value is not set.
Note: two test cases in Git's test suite want to verify that the
`stderr` output of `git init` is empty. It is now necessary to suppress
the advice, we now do that via the `init.defaultBranch` setting. While
not strictly necessary, we also set this to `false` in
`test_create_repo()`.

We are about to introduce a message giving users running `git init` some
advice about `init.defaultBranch`. This will necessarily be done in
`repo_default_branch_name()`.
Not all code paths want to show that advice, though. In particular, the
`git clone` codepath _specifically_ asks for `init_db()` to be quiet,
via the `INIT_DB_QUIET` flag.
In preparation for showing users above-mentioned advice, let's change
the function signature of `get_default_branch_name()` to accept the
parameter `quiet`.

In one of the next commits, we would like to give users some advice
regarding the initial branch name, and how to modify it.
To that end, it would be good if `git branch -m <name>` worked in a
freshly initialized repository without any commits. Let's make it so.

Our documentation does not mention any future plan to change 'master' to
other value. It is a good idea to document this, though.

In 83bbf9b92ea8 (mergetool--lib: improve support for vimdiff-style tool
variants, 2020-07-29), we introduced a `list_tool_variants` function
in the spirit of Postel's Law: be lenient in what you accept as input.
In this particular instance, we wanted to allow not only `bc` but also
`bc3` as name for the Beyond Compare tool.
However, what this patch overlooked is that it is totally allowed for
users to override the defaults in `mergetools/`. But now that we strip
off trailing digits, the name that the user gave the tool might not
actually be in the list produced by `list_tool_variants`.
So let's do the same as for the `diff_cmd` and the `merge_cmd`: override
it with the trivial version in case a user-defined setup was detected.

As of 83bbf9b92ea8 (mergetool--lib: improve support for vimdiff-style
tool variants, 2020-07-29), we already list `bc` and `bc3` as aliases
for that mergetool/difftool.
However, the current Beyond Compare version is _4_, therefore the `bc4`
alias is missing from that list.
Most notably, this is the root cause of the breakage reported in
https://github.com/git-for-windows/git/issues/2893 where a
well-configured `bc4` difftool stopped working as of v2.29.0:
`setup_tool` would notice that after stripping off the trailing digit,
it finds a match in `mergetools/` (the `bc` file), source it, and then
the alias would not match the list offered by the `list_tool_variants`
function, and simply exit without doing anything, but pretending
success.

Now that hashamp has lazy initialization and a HASHMAP_INIT macro,
hashmaps allocated on the stack can be initialized without a call to
hashmap_init() and in some cases makes the code a bit shorter. Convert
some callsites over to take advantage of this.

By default, we do not use a mempool and strdup_strings is true; in this
case, we can avoid both an extra allocation and an extra free by just
over-allocating for the strmap_entry leaving enough space at the end to
copy the key. FLEXPTR_ALLOC_STR exists for exactly this purpose, so
make use of it.
Also, adjust the case when we are using a memory pool and strdup_strings
is true to just do one allocation from the memory pool instead of two so
that the strmap_clear() and strmap_remove() code can just avoid freeing
the key in all cases.

In 1af265f0 (compat/bswap.h: simplify MSVC endianness
detection, 2020-11-08) we attempted to simplify code by assuming MSVC
builds will be for little-endian machines, since only unusably old
versions of MSVC supported big-endian MIPS and m68k architectures.
However, it's possible that MSVC could be ported to build for a
big-endian architecture again, so the simplification wasn't as
future-proof as hoped.
So let's go back to the old way of detecting MSVC, and then checking
architecture from a list of little-endian architecture macros.
Note that MSVC does not treat ARM64 as bi-endian, so we can safely treat
it as little-endian.
