All the compilers should provide the header file by now. Remove `tr_isBool`
sanity checks along the way as compiler should guarantee that bool (_Bool)
values are 0 or 1 and nothing else.
In systemd v209, released over two years ago, the various libsystemd-*
libraries (libsystemd-journal.so, libsystemd-login.so, libsystem-daemon.so,
libsystemd-id128.so) were merged into a single libsystemd.so library to
reduce code duplication and avoid cyclic dependencies.
Implement BSD/Darwin (kqueue) and Windows (ReadDirectoryChanges) mechanisms
for receiving directory change notifications. Use events instead of polling
for changes. Retry file parsing up to 3 times before giving up.
Huge thanks to missionsix for preparing first two versions of the patch.
Now that MSVC support for C99 is quite good, remove previously needed but
now unused checks and definitions, like PRI* format macros (including
PRIdMAX and TR_PRIuSIZE, replaced with %jd and %zu) and inline macro.
Also, remove ssize_t typedef and replace few occurences with ev_ssize_t.
Also, remove check for stdbool.h availability (guaranteed by C99) and
include it unconditionally (except when in C++ mode).
There're too many functions and types to consider, and benefits of not
using LFS macros aren't that big (I was thinking of using fts(3) but
that may not happen soon or at all).
Remove BASE64 reference testing as it's only libb64 now.
Improve the test to ignore \r and \n when comparing BASE-encoded
strings to not fail on system (unpatched) libb64.
Some crypto libraries (like CyaSSL, MatrixSSL and CommonCrypto) either
don't have or expose this functionality at all, expose only part of it,
or (like OpenSSL) have heavyweight API for it. Also, for the task as
easy as BASE64 encoding and decoding it's much better to use small and
simple specialized library.
This should not affect non-Win32 platforms in any way.
As for Win32 (both MinGW and MSVC), this should hopefully allow for
unpatched compilation. Correct functioning is not yet guaranteed though.
