HPCC-12127 Use 64-bit integer for HTTP Content-Length header

In the existing ESP code, two member variables are used to store
and set HTTP Content-Length header: m_content_length64 (int64)
and m_content_length (int). When an HTTP message content is very
large, m_content_length may have an incorrect value. ESP fails
to download a >4G file due to the incorrect value. This fix
changes the m_content_length to be int64 and replaces the
m_content_length64 with the m_content_length.

HPCC-12338 If localThor adjust slave/master default memory

Previously defaults were for both to grab 75%, which is 'ok' on
a standard distro. with overcommit_memory set to 0.
In practice the master rarely uses that much, so on a single node
system it wasn't an issue, however if overcommit_memory is = 2
Then master or slaves will fail with an error reserving memory.
