Yasio uses double newline in logs

[smilediver]

Yasio always logs with a double newline adding empty lines:

[yasio][1718380710550][global] the yasio-4.2.2 is initialized, the size of per transport is 65864 when object_pool enabled.

[yasio][1718380710550][global] sizeof(io_event)=80

[yasio][1718380962389][index: 0] start query 127.0.0.1...

The issue is that one newline is added when formatting the log string here:

axmol/3rdparty/yasio/yasio/io_service.cpp

Line 76 in 1a39fbf

auto __msg = ::yasio::strfmt(127, "[yasio][%lld]" format "\n", ::yasio::clock<system_clock_t>(), ##__VA_ARGS__); \

Then another one is added when printing here:

axmol/3rdparty/yasio/yasio/logging.hpp

Line 44 in 1a39fbf

# define YASIO_LOG_TAG(tag, format, ...) printf((tag format "\n"), ##__VA_ARGS__)

I'm not sure which one should be removed, but my guess would be the one in printf.

This is probably affected by the same issue too:

axmol/3rdparty/yasio/yasio/logging.hpp

Line 38 in 1a39fbf

# define YASIO_LOG_TAG(tag, format, ...) OutputDebugStringA(::yasio::strfmt(127, (tag format "\n"), ##__VA_ARGS__).c_str())
