Use the same approach as for GMP: If no explicit directory is
given, assume it must be on the default include path and libdir.
Otherwise use the provided path. It does not look like libsybdb
has support for pkg-config.
`version_compare()` does a sloppy check for the `$operators` argument
which allows arbitrary abbreviations of the supported operators to be
accepted. This is both undocumented and unexpected, and could lead to
subtle BC breaks, if the order of the comparisions will be changed.
Therefore we change to strict comparisons.
Closes GH-6510.
The concrete need on this change is to support passing an initial seed
to the murmur hash. Passing a custom seed is important in terms of
randomizing the hash function.
The suggested implementation adds a HashTable parameter to all the
init callbacks. Further on, an array with custom arguments is accepted
from `hash` or `hash_init` from the user land. Currently several things
like `hash_hkdf` are not touched, as they don't need passing custom
args.
Some convenience macros have been added to the SHA/MD families of
functions, so the consuming code doesn't have to be changed widely.
Another way to implement this is to add another type of the init that
would accept a HT with arguments. However, that would still require
touching all the context structs in all the algos. That would also
increase the size of those structs. As an init function is called just
once, the way of modifying the existing init callback has been seen
as more preferrable.
Closes GH-6400.

libmysqlclient added this function in version 5.5, which happens
to be the minimum we support. If we have a prepared statement,
we should use it on both mysqlnd and libmysqlclient, even if the
handling afterwards is different.
This fixes error handling with native prepared statements.
The fact that getAttribute() fails for various libmysqlclient-only
options is a known issue, and the test was taking that into account.
However, the change of the default error mode broke the handling.
We need to handle the exceptions now.
Our minimum libmysqlclient version requirement is high enough
that we don't need to check for MYSQL_OPT_LOCAL_INFILE support.
However, the mysql_get_option() function seems to only be available
since 5.7 (though it's really hard to find any definitie information
on when MySQL introduced certain functions or changes...) so we
need to store the value of the flag locally to make it available
through getAttribute().
stmt->column_count gets reset before the next_rowset handler is
invoked, so we need to fetch the value from the result set instead.
Arguably PDO should be separating the destruction of the previous
result set and the switch to the next result set more cleanly...
Generate a param count mismatch error even if the query contains
no placeholders.
Additionally we shouldn't HANDLE errors from pdo_parse_params,
which are always reported via raise_impl_error. Doing so results
in duplicate error messages.
When a driver reports an error during EVT_ALLOC (and some over EVTs),
make sure we handle it as usual, i.e. warn or throw.
This requires some adjustments in PDO PgSQL to stop manually doing
this through an impl error.
Unfortunately the PDO PgSQL error messages regress because of this,
as they now include a completely arbitrary error code. There doesn't
seem to be an ability to skip it right now.
The actual behavior here is correct, but the previous error
message was misleading, as neither fetchAll() nor buffered queries
would help in this situation. Instead it is necessary to consume
all rowsets, which can be done by either unsetting the statement
or calling closeCursor().
When we receive an error while reading a result set, we should
assume that no more result sets are available. libmysqlclient
implements the same behavior.
