Benchmarking framework, loosely based on google's micro-benchmarking
library (https://github.com/google/benchmark)
Wny not use the Google Benchmark framework? Because adding Even More Dependencies
isn't worth it. If we get a dozen or three benchmarks and need nanosecond-accurate
timings of threaded code then switching to the full-blown Google Benchmark library
should be considered.
The benchmark framework is hard-coded to run each benchmark for one wall-clock second,
and then spits out .csv-format timing information to stdout. It is left as an
exercise for later (or maybe never) to add command-line arguments to specify which
benchmark(s) to run, how long to run them for, how to format results, etc etc etc.
Again, see the Google Benchmark framework for where that might end up.
See src/bench/MilliSleep.cpp for a sanity-test benchmark that just benchmarks
'sleep 100 milliseconds.'
To compile and run benchmarks:
cd src; make bench
Sample output:
Benchmark,count,min,max,average
Sleep100ms,10,0.101854,0.105059,0.103881

Bugfix: Add missing zmq header includes
Bugfix: Adjust build system to link ZeroMQ code for Qt binaries
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.
Three changes to how configure --enable-debug behaves:
1. Preserve user-passed CXXFLAGS/CFLAGS
2. Compile with -DDEBUG_LOCKORDER
3. Add -DDEBUG -DDEBUG_LOCKORDER to CPPFLAGS (since they are preprocessor options)
Until secp256k1 is used for verification there is no reason for Bitcoin
Core's secp256k1 to link against gmp, even if available. Pass a flag to
configure to override the bignum implementation.
This fixes a crash at runtime on ppc64 reported by @gmaxwell.
- Detect endian instead of stopping configure on big-endian
- Add `byteswap.h` and `endian.h` header for compatibility with
Windows and other operating systems that don't come with them
- Update `crypto/common.h` functions to use compat
endian header
This was added a while ago for testing purposes, but was never intended to be
used. Remove it until upstream libsecp256k1 decides that verification is
stable/ready.
Backwards-compatibility for libstdc++ is not limited to straightforward abi
changes. Symbol visibility also needs to be taken into consideration, and
that really can't be addressed simply.
Instead, just static-link libstdc++ for backwards-compat.
This is really a packager's option. While it's helpful to encourage devs to
test this option for daily builds, it's not reliable in several real-world
use-cases. Some older libstdc++ runtimes (freebsd 9, debian wheezy, for
example) fail to properly catch exceptions due to mismatched type_info.
See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=19664 for more info.

Similar to the INCLUDES changes in 6b099402b4, split out LIBS into individual
entries for more fine-grained control.
Also add MINIUPNPC_LIBS which was missing before, and hook it up to
executables.
Qt5 is bottled, so configure won't find it without some help. Use
brew to find out its prefix.
Also, qt5 added the host_bins variable to pkg-config, use it.
Windows needed a few fixups to get the tests running:
1. bitcoin-tx needs a file extension in Windows. Take this opportunity to
add an env file, which pulls variables out of our build config. This can
be extended as needed, for now it's very simple.
2. After #1, split the args out of the exec key in the test data.
3. Correct the line-endings from windows stdout

9f7f504 build: add -DMINIUPNP_STATICLIB for new version (Cory Fields)
It's only confusing people into thinking that they should mess with
boost versions, which should not be necessary to get bitcoind to work.
If there is a bug in the build system with autodetecting boost it needs
to be solved not worked around.
libminiupnpc changed their required static define to the much more sane
"MINIUPNP_STATICLIB". Sadly, they don't respect the old "STATICLIB" for
back-compat. Define them both since the old one didn't seem to be conflicting
anywhere.
Also go ahead and split out the cppflags so that they can be applied only where
they're needed. This will help us to build dll's from our libs without having
their import/export declspecs poisoned.
When using clang and ccache, builds spew lots of:
Clang: warning: argument unused during compilation
Upstream bug: https://bugzilla.samba.org/show_bug.cgi?id=8118
This is harmless, bug annoying. If ccache is being used and the
-Qunused-arguments flag is supported (clang), use it.
This was committed previously as 4975ae172 and reverted, because the flags were
applied even if the checks didn't pass. This is the same commit, fixed up to
actually disable the functionality when necessary.
Enabled automatically if boost >= 1.49.
See: https://svn.boost.org/trac/boost/ticket/2309
Also, check for a default visibility attribute, so that we can mark future
api functions correctly.

While we're at it, reduce the use of LIBS as well. This makes dependencies
explicit.
Fixes building with (the not-yet-merged) libsecp256k1 as well.

If clock_gettime is implemented outside of libc (librt in this case), configure
would fail when testing boost. Since clock_gettime is not present on all OSs,
boost only uses it when it can. Check for it in librt and add it to LIBS if
found, but don't fail if it's not (since boost won't be expecting it in this
case).
Also, reverse the link order as necessary for static libs.
Note that it's possible that there are other similar cases for boost, which may
be handled the same way.
This is the first part of a huge effort to rework the handling of dependencies.
To start, this change allows all supported platforms to build against a static
Qt. 5.2.1 and 5.3 have been successfully tested against osx64, win32, win64,
linux32, and linux64.
It also makes a small change to the windows config, to allow linking against
qt builds with or without built-in libjpeg/libpng/libpcre/libz.
The actual build processes to take advantage of these changes (for gitian and
pull-tester) are coming soon. Until then, this should be a no-op.
Note: This is added to our existing automake targets rather than as a
libtool-style lib. The switch to libtool-style targets can come later if it
proves to not add any complications.
In the LookupIntern(), things changed are:
1. Call getaddrinfo_a() instead of getaddrinfo() if available, the former is a sync version of the latter;
2. Try using inet_pton()/inet_addr() to convert the input text to a network addr structure at first, if success the extra name resolving thread inside getaddrinfo_a() could be avoided;
3. An interruption point added in the waiting loop for return from getaddrinfo_a(), which completes the improve for thread responsiveness.
A easy way to see the effect is to kick off a 'bitcoind stop' immediately after 'bitcoind -daemon', before the change it would take several, or even tens of, minutes on a bad network situation to wait for the running bitcoind to exit, now it costs only seconds.

Build logic moves from individual Makefile.am's to include files, which
the main src/Makefile.am includes. This avoids having to manage a gigantic
single Makefile.
TODO: Move the rules from the old Makefile.include to where they actually
belong and nuke the old file.
Log the name of the error as well as the error code if a network problem
happens. This makes network troubleshooting more convenient.
Use thread-safe strerror_r and the WIN32 equivalent FormatMessage.
The year is 2014. All supported operating systems have IPv6 support,
most certainly at build time (this doesn't mean that IPv6 is configured,
of course).
If noone is exercising the functionality to disable it, that means it
doesn't get tested, and IMO it's better to get rid of it.
(it's also not used consistently in RPC/boost and Net code...)
