gitian: Make linux build of OpenSSL deterministic

OpenSSL was embedding a timestamp causing its build to be
non-deterministic.
Change deps-linux to be deterministic by using FAKETIME
as needed and disabling it when it gets in the way.
gitian: Make linux boost dependency completely deterministic

It appears that the output was different every time.

This doesn't affect the final bitcoind/bitcoin-qt, but is confusing
nevertheless.

Fix it by using FAKETIME and zipping files in deterministic order.
gitian: Make windows dependencies outputs fully deterministic

Sort .zip order, and other determinism changes to make sure builds
are repeatable for windows deps.
Log warnings when bootstrap files are specified but cannot be opened

- Log a warning when bootstrap files are specified using `-loadblock`
but cannot be opened.
- Log a warning when bootstrap.dat exists in the home directory
but cannot be opened.

contrib/devtools/fix-copyright-headers.py script to be able to perform this maintenance task with ease during the rest of the year, every year. Modifications to contrib/devtools/README.md to document what fix-copyright-headers.py does.
gitian: Sort generated source distribution archive

Sort the filenames in the resulting tar, normalize the time/date
and user/group information.
gitian: add -D flag to ar for deterministic output for linux deps

ar -D: Operate in deterministic mode. When adding files and the archive
index use zero for UIDs, GIDs, timestamps, and use consistent file modes
for all files.  When this option is used, if ar is used with identical
options and identical input files, multiple runs will create identical
output files regardless of the input files' owners, groups, file modes,
or modification times.
gitian: Post-process .a libraries for win to be deterministic

1bbca24 Add option to avoid spending unconfirmed change (Wladimir J. van der Laan)
If requested, actually treat uncomfirmed change as being uncomfirmed

This commit strengthens 1bbca249b202c4802cc2c4d4de4a26e6392b4d92 by updating the CWalletTx::IsConfirmed() function.

If (bSpendZeroConfChange==false), then IsConfirmed() should actually treat unconfirmed change as being unconfirmed.
Rename IsConfirmed to IsTrusted to better match the intended behavior.

This doesn't change the functionality at all.
