None of the current integer parsing functions in util
check whether the result is valid and fits in the range
of the type. This is required for less sloppy error reporting.

Help text appears to have been copy/pasted from getrawtransaction,
so it erroneously asked for a txid where rawtransaction hex should appear.
Remove lines which were copy/pasted from getrawtransaction but which
aren't displayed by decoderawtransaction.

redeemScripts >520bytes can't be spent due to the
MAX_SCRIPT_ELEMENT_SIZE limit; previously the addmultisigaddress and
createmultisig RPC calls would let you violate that limit unknowingly.
Also made the wallet code itself check the redeemScript prior to adding
it to the wallet, which in the (rare) instance that a user has added an
invalid oversized redeemScript to their wallet causes an error on
startup. The affected key isn't added to the wallet; other keys are
unaffected.
Removes the limits on number of pubkeys for P2SH CHECKMULTISIG outputs.
Previously with the 500 byte scriptSig limit there were odd restrictions
where even a 1-of-12 P2SH could be spent in a standard transaction(1),
yet multisig scriptPubKey's requiring more signatures quickly ran out of
scriptSig space.
From a "stuff-data-in-the-blockchain" point of view not much has changed
as with the prior commit now only allowing the dummy value to be null
the newly allowed scriptSig space can only be used for signatures. In
any case, just using more outputs is trivial and doesn't cost much.

Mined by BTC Guild.
This is a source of transaction mutability as the dummy value was
previously not checked and could be modified to something other than the
usual OP_0 value.
- replaces checks in SendCoinsDialog::handlePaymentRequest() that belong
to PaymentServer (normal URIs are special cased, as only an isValid
check is done on BTC addresses)
- prevents the client to handle payment requests that do not match the
clients network and shows an error instead (mainly a problem with
drag&drop payment requests onto the client window)
- includes some small comment changes also
Size specifiers are no longer needed now that we use typesafe tinyformat
for string formatting, instead of the system's sprintf.
No functional changes.
This continues the work in #3735.
- fixes error from debug.log:
QMetaObject::connectSlotsByName: No matching signal for
on_recentRequestsView_selectionChanged(QItemSelection,QItemSelection)
- small style fixes (e.g. alphabetical ordering if includes etc.)
- fixes#3992
Generally useless information. Only updates on connect time, not after
that. Peers can easily lie and the median filter is not effective in
preventing that.
In the past it was used for progress display in the GUI but
`CheckPoints::guessVerificationProgress` provides a better way that is now used.
It was too easy to mislead it. Peers do lie about it in practice, see issue #4065.
From the RPC, `getpeerinfo` gives the peer raw values, which are more
useful.
Adds two new info query commands that take over information from
hodge-podge `getinfo`.
Also some new information is added:
- `getblockchaininfo`
- `chain`: (string) current chain (main, testnet3, regtest)
- `verificationprogress: (numeric) estimated verification progress
- `chainwork`
- `getnetworkinfo`
- `localaddresses`: (array) local addresses, from mapLocalHost (fixes#1734)
There is no need to use any specific version of boost on Linux/Unix.
Even 1.37 should still work.
Also the mention of boost-dev doesn't belong after adding oldstable.
Remove it. libboost-all-dev is already mentioned earlier.
If the `libqt4-dev` package is installed it picks the moc executable
from the system instead of our custom-built one. This results in
compatibility errors.
This commit convinces configure to pick the right one.
