use shared libraries

[milahu]

i want to link nano-node against shared libraries, to speed up the build process

so effectively, i have reverted #4030 (and some other commits)

this PR should not be merged in its current form
because most package managers dont allow pinning dependencies like nix or guix

ideally, there should be a build option like USE_SHARED_LIBS
and the CMakeLists.txt should have separate branches for static or shared build

Error: logging should be initialized before creating a logger

fixed: runtime error: Error: logging should be initialized before creating a logger

the build is passing, but now i get this error on runtime... ideas?

Aborted (core dumped)

it works as expected with the nano-node with gitmodules build
(nixpkgs has only nano-wallet but not the full nano-node, dont ask me why)

nix-shell -p nano-wallet
nano_wallet

my build script is nano-node.nix

you will need nix to run that build script

git clone --depth=1 https://github.com/milahu/nur-packages
cd nur-packages
nix-build . -A nano-node
./result/bin/nano_wallet

it seems like nano::logger::initialize is not called

nano::logger was added in #4375 by @pwojcikdev

nano/lib/logging.cpp

void nano::logger::initialize (nano::log_config fallback, std::optional<std::filesystem::path> data_path, std::vector<std::string> const & config_overrides)
{
        // Only load log config from file if data_path is available (i.e. not running in cli mode)
        nano::log_config config = data_path ? nano::load_log_config (fallback, *data_path, config_overrides) : fallback;
        initialize_common (config, data_path);
        global_initialized = true;
}

so nano::logger::logger fails

nano::logger::logger (std::string identifier) :
  identifier{ std::move (identifier) }
{
  release_assert (global_initialized, "logging should be initialized before creating a logger");
}

but nano::logger::initialize should be called from nano/nano_wallet/entry.cpp

int main (int argc, char * const * argv)
{
  nano::set_umask (); // Make sure the process umask is set before any files are created
  nano::initialize_file_descriptor_limit ();
  nano::logger::initialize (nano::log_config::cli_default ());

so nano::logger::logger is called by

#5 0x0000000000499450 in __static_initialization_and_destruction_0 () at /build/source/nano/nano_wallet/entry.cpp:28

nano/nano_wallet/entry.cpp

namespace
{
nano::logger logger{ "wallet_daemon" };

im surprised that this works in the original version (does it?)

backport to V26.0

i tried to backport this patch to V26.0 as a workaround for #4680 (comment)
but this fails to build with dynamic boost libraries

undefined reference to `boost::log::v2_mt_posix::sinks::text_file_backend::~text_file_backend()'

see also #269

boost::log was removed in #4030 = V26.1
and without boost::log the build just works with dynamic boost libraries
