Use Character.isWhitespace() instead of Character.isSpaceChar() to
treat TABs as whitespace, too.

Negated patterns were handled wrongly. According to the OpenBSD
ssh_config man page,[1] a negated pattern never matches. Negated
patterns make only sense if there are positive patterns; the
negated pattern then can define exceptions for the positive
patterns.
OpenSshConfigFile did this wrongly. It handled "!foo" as "matching
everything but foo", but actually the semantics is "if the input is
"foo", this entry doesn't apply. If the input is anything else,
other patterns determine whether the entry may apply.".

OpenSSH 8.4 has introduced simple environment variable substitution
for some keys. Implement that feature in our ssh config file parser,
too.

OpenSSH has changed some things in ssh config files. Update our parser
to implement some of these changes:
* ignore trailing comments on a line
* rename PubkeyAcceptedKeyTypes to PubkeyAcceptedAlgorithms
Note that for the rename, openSSH still accepts both names. We do the
same, translating names whenever we get or set values.

Make all transports request protocol V2 when fetching. Depending on
the transport, set the GIT_PROTOCOL environment variable (file and
ssh), pass the Git-Protocol header (http), or set the hidden
"\0version=2\0" (git anon). We'll fall back to V0 if the server
doesn't reply with a version 2 answer.
A user can control which protocol the client requests via the git
config protocol.version; if not set, JGit requests protocol V2 for
fetching. Pushing always uses protocol V0 still.
In the API, there is only a new Transport.openFetch() version that
takes a collection of RefSpecs plus additional patterns to construct
the Ref prefixes for the "ls-refs" command in protocol V2. If none
are given, the server will still advertise all refs, even in protocol
V2.
BasePackConnection.readAdvertisedRefs() handles falling back to
protocol V0. It newly returns true if V0 was used and the advertised
refs were read, and false if V2 is used and an explicit "ls-refs" is
needed. (This can't be done transparently inside readAdvertisedRefs()
because a "stateless RPC" transport like TransportHttp may need to
open a new connection for writing.)
BasePackFetchConnection implements the changes needed for the protocol
V2 "fetch" command (stateless protocol, simplified ACK handling,
delimiters, section headers).
In TransportHttp, change readSmartHeaders() to also recognize the
"version 2" packet line as a valid smart server indication.
Adapt tests, and run all the HTTP tests not only with both HTTP
connection factories (JDK and Apache HttpClient) but also with both
protocol V0 and V2. The SSH tests are much slower and much more
focused on the SSH protocol and SSH key handling. Factor out two
very simple cloning and pulling tests and make those run with
protocol V2.

Do not export the test-only package org.eclipse.jgit.transport from
bundle org.eclipse.jgit.ssh.jsch.test. Doing so can confuse the build
in Eclipse: other bundles that import this package may then also pick
up this test package, leading to non-test sources depending on test
sources and to build cycles.

It seems Eclipse 4.18 reports them as error whereas earlier versions
ignored this maybe since we don't require javadoc comments for all the
test bundles.

Revert "Client-side protocol V2 support for fetching"
This reverts commit f802f06e7f.
I had misunderstood how protocol V2 works. This implementation only
works if the negotiation during fetch is done in one round.
Fixing this is substantial work in BasePackFetchConnection. Basically
I think I'd have to change back negotiate to the V0 version, and have
a doFetch() that does
if protocol V2
doFetchV2()
else
doFetchV0()
with doFetchV0 the old code, and doFetchV2 completely new.
Plus there would need to be a HTTP test case requiring several
negotiation rounds.
This is a couple of days work at least, and I don't know when I will
have the time to revisit this. So although the rest of the code is
fine I prefer to back this out completely and not leave a only half
working implementation in the code for an indeterminate time.
