MySQL dictionary source: A mechanism for retrying unexpected connection loss during communication with mysql server (#21237)
* Added a new type of Exception

for better recognition of connection failures

* Added more logging for mysql communication

* Retries on connection loss during query.

Make MySQL dictionary source resilient to unexpected loss of connection
during querying MySQL. This behavior is controlled with
".fail_on_connection_loss" config parameter, which defaults to false.

* Stripped some debugging leftover garbage

* Minor followup corrections

* Corrections after PR comments

* Yet more fixes

810023a65c Do not undefine __has_feature (may break c++ headers)
If the order of <common/defines.h> and c++ header will be wrong the
compilation will be broken.

v2: rename __ch_has_feature to ch_has_feature to fix -Wreserved-id-macro
v3: do not fallback to 0

8ab578065a Fix __has_feature macros under gcc
__has_feature supported only by clang.

But libcxx/libcxxabi overrides it to 0:

    $ fgrep -r 'define __has_feature' contrib/libcxx*
    contrib/libcxx/include/__config:#define __has_feature(__x) 0
    contrib/libcxxabi/src/demangle/DemangleConfig.h:#define __has_feature(x) 0

Thus the checks for __has_feature will be wrong, undefine it again to
avoid such issues.

This will also fix building with sanitizers under gcc (before this patch
BOOST_USE_UCONTEXT wasn't set for sanitizers).

7474a7e3ca Increase buffer for uncaught exception / std::terminate
Use PIPE_BUF over some magic number 1024 in terminate_handler, since
according to pipe(7):

    PIPE_BUF
           POSIX.1  says  that  write(2)s of less than PIPE_BUF bytes must be atomic

Also note that 1024, is too small, especially for C++ stacktraces (and
especially for debug builds, that contains lots of non-inlined helpers
for various ptrs).
