Fix error occurring when SecurityManager is enabled
It's expected that jgit should work without native git installation.
In such case Security Manager can be configured to deny access to the
files outside of git repository. JGit tries to find cygwin
installation. If Security manager restricts access to some folders
in PATH, it should be considered that those folders are absent
for jgit.
Also JGit tries to detect if symbolic links are supported by OS. If
security manager forbids creation of symlinks, it should be assumed
that symlinks aren't supported.

Avoid sign extension when comparing mtime with Instant#getEpochSecond
Ensure we use the same type when comparing seconds since the epoch.
This does not prevent that in 2038 timestamps in seconds since the epoch
stored in a 32 bit integer will overflow. Integer.MAX_VALUE translates
to 2038-01-19T03:14:07Z. After this date we'll have an issue since we
store seconds since the epoch in a 32 bit integer in some places.

UploadPack: support custom packfile-to-URI mapping
Teach UploadPack to take a provider of URIs corresponding to cached
packs. When fetching, if the client supports the packfile-uri feature,
and if such a cached pack were to be streamed, instead send the
corresponding URI.
This packfile-uri feature is implemented in the jt/fetch-cdn-offload
branch of Git. There is interest in this feature [1], but it is not yet
merged.

reftable: fix seeking to refs in reflog implementation
Small reftables omit the log index. Currently,
ReftableWriter#shouldHaveIndex does this if there is a single-block
log, but other writers could decide on different criteria.
In the case that the log index is missing, we have to linearly search
for the right block. It is never appropriate to use binary search on
blocks for log data, as the blocks are compressed and therefore
irregularly sized.

Cache user global and system-wide git configurations
So far the git configuration and the system wide git configuration were
always reloaded when jgit accessed these global configuration files to
access global configuration options which are not in the context of a
single git repository. Cache these configurations in SystemReader and
only reload them if their file metadata observed using FileSnapshot
indicates a modification.

GPG: also consider pubring.gpg when looking for keys
The algorithm for finding keys was already improved in commit db0eb9f8,
but that wasn't quite correct yet.
If there is no pubring.kbx but a private-keys-v1.d directory and a
pubring.gpg, GPG also uses pubring.gpg in combination with the
private-keys-v1.d directory. GPG has three ways to locate public and
private key pairs:
* pubring.kbx and private-keys-v1.d (GPG >= 2.1)
* pubring.gpg and private-keys-v1.d (GPG >= 2.1)
* pubring.gpg and secring.gpg (GPG < 2.1)
See [1] and [2]. pubring.kbx may not exist if the user migrated from
an older GPG installation and didn't run the agent. Since we don't
know which GPG version the user has we must try secring.gpg also if
we found the public key in pubring.gpg, but didn't find the secret
key in the private key directory. Note that GPG < 2.1 also may have
a private key directory, used by the agent. But it may also _not_ have
that directory.

Remove FileBasedConfig.load(boolean) introduced in d45219ba
We can't add this method to the super class StoredConfig since that
abstracts from filesystem storage. MockSystemReader.MockConfig is a
StoredConfig and is also used by tests for dfs based storage. Hence
remove this leaky abstraction.
This implies we always use the fallback FileStoreAttributes which means
a config file modification is considered racy within the first 2
seconds. This should not be an issue since typically configs change
rarely and re-reading a config within the racy period is relatively
cheap since configs are small.
