detail::read_content_chunked was using std::stoul to parse the
hexadecimal chunk lengths for "Transfer-Encoding: chunked" requests.
This throws an exception if the string does not begin with any valid
digits. read_content_chunked is not called in the context of a try block
so this caused the process to terminate.
Rather than use exceptions, I opted for std::stroul, which is similar to
std::stoul but does not throw exceptions. Since malformed user input is
not particularly exceptional, and some projects are compiled without
exception support, this approach seems both more portable and more
correct.

* SSLClient: add constructor to pass ssl-certificates and key from memory
* add TestCase for passing certificates from memory to SSLClient/SSLServer
Previously, calling set_content always resulted in 's' being copied. With this change, there will still be the same number of copies made (1) when doing `set_content(my_value, ...)`, but there will be no copies if a caller elects to do `set_content(std::move(value), ...)` or `set_content(some_function_that_returns_a_temporary(), ...)` instead.
The regex that parses header lines potentially causes an unlimited
amount of backtracking, which can cause an exception in the libc++ regex
engine.
The exception that occurs looks like this and is identical to the
message of the exception fixed in
https://github.com/yhirose/cpp-httplib/pull/280:
libc++abi.dylib: terminating with uncaught exception of type
std::__1::regex_error: The complexity of an attempted match
against a regular expression exceeded a pre-set level.
This commit eliminates the problematic backtracking.
