To bridge the time until a dynamic method for determining this fee is
merged.
This is especially aimed at the stable releases (0.10, 0.11) because
full mempool limiting, as will be in 0.12, is too invasive and risky to
backport.

Common sentiment is that the miniupnpc codebase likely contains further
vulnerabilities.
I'd prefer to get rid of the dependency completely, but a compromise for
now is to at least disable it by default.

This adds SCRIPT_VERIFY_LOW_S to STANDARD_SCRIPT_VERIFY_FLAGS which
will make the node require the canonical 'low-s' encoding for
ECDSA signatures when relaying or mining.
Consensus behavior is unchanged.
The rational is explained in a81cd96805ce6b65cca3a40ebbd3b2eb428abb7b:
Absent this kind of test ECDSA is not a strong signature as given
a valid signature {r, s} both that value and {r, -s mod n} are valid.
These two encodings have different hashes allowing third parties a
vector to change users txids. These attacks are avoided by picking
a particular form as canonical and rejecting the other form(s); in
the of the LOW_S rule, the smaller of the two possible S values is
used.
If widely deployed this change would eliminate the last remaining
known vector for nuisance malleability on boring SIGHASH_ALL
p2pkh transactions. On the down-side it will block most
transactions made by sufficiently out of date software.
Unlike the other avenues to change txids on boring transactions this
one was randomly violated by all deployed bitcoin software prior to
its discovery. So, while other malleability vectors where made
non-standard as soon as they were discovered, this one has remained
permitted. Even BIP62 did not propose applying this rule to
old version transactions, but conforming implementations have become
much more common since BIP62 was initially written.
Bitcoin Core has produced compatible signatures since a28fb70e in
September 2013, but this didn't make it into a release until 0.9
in March 2014; Bitcoinj has done so for a similar span of time.
Bitcoinjs and electrum have been more recently updated.
This does not replace the need for BIP62 or similar, as miners can
still cooperate to break transactions. Nor does it replace the
need for wallet software to handle malleability sanely[1]. This
only eliminates the cheap and irritating DOS attack.

When running the rpc tests in Wine, nodes often fail to listen on localhost
due to a stale socket from a previous run. This aligns the behavior with other
platforms.
Add error checking to CLevelDBWrapper for errors from
leveldb::DestroyDB(). Without it, if unlink() or DeleteFileW() fail to
delete files, they will fail silent. If they fail to delete any files,
CLevelDBWrapper will silently open and read the existing database.
Typically any permissions issues would be caught by leveldb as it churns
through many files as part of its compaction process, but it is
conceivable that this could cause problems on Windows with anti-virus
and indexing software.
Checking libcrypto for a function after we've already found a (possibly
different) libcrypto is not what we want to do here.
pkg-config might've found a cross lib while AC_CHECK_LIB may find a different
or native one.
Run a link-test against the lib that's already been found instead.
Move from sourceforge to linux foundation.
Also get rid of some other stale mentions of sourceforge.

Make it possible to opt-out of the centralized alert system by providing
an option `-noalerts` or `-alerts=0`. The default remains unchanged.
This is a gentler form of #6260, in which I went a bit overboard by
removing the alert system completely.
I intend to add this to the GUI options in another pull after this.

Chance "getbalance *" not to use IsTrusted. The method and result
now match the "getbalance <specific-account>" behavior. In
particular, "getbalance * 0" now works.
Also fixed a comment -- GetGalance has required 1 confirmation
for many years, and the default "getbalance *" behavior matches
that.

Change `read_string` to fail when not the entire input has been
consumed. This avoids unexpected, even dangerous behavior (fixes#6223).
The new JSON parser adapted in #6121 also solves this problem so in
master this is a temporary fix, but should be backported to older releases.
Also adds tests for the new behavior.

Fix two CSubNet constructor problems:
- The use of `/x` where 8 does not divide x was broken, due to a
bit-order issue
- The use of e.g. `1.2.3.4/24` where the netmasked bits in the network
are not 0 was broken. Fix this by explicitly normalizing the netwok
according to the bitmask.
Also add tests for these cases.
Fixes#6179. Thanks to @jonasschnelli for reporting and initial fix.
