Let gdb handle the control-c instead of killing winedbg.

All integer code assume CPU of debuggee encode integers:
- little endian
- 2 complement for signed integers.

As a side effect, the internal 'long int' type is now always 8 byte wide.

Today, when gdbproxy is started with --no-start mode, GDB fails to
recognise the symbol file unless the `file` command or the
`sharedlibrary` command is explicitly issued.
Also, RHEL's downstream GDB complains with the following message:
Remote gdbserver does not support determining executable automatically.
RHEL <=6.8 and <=7.2 versions of gdbserver do not support such automatic executable detection.
The following versions of gdbserver support it:
- Upstream version of gdbserver (unsupported) 7.10 or later
- Red Hat Developer Toolset (DTS) version of gdbserver from DTS 4.0 or later (only on x86_64)
- RHEL-7.3 versions of gdbserver (on any architecture)
Fix this by implementing the qXfer object "exec-file".

GDB does not retrieve the result of a qXfer command at once; instead, it
issues a series of requests to obtain the result one "chunk" at a time,
and concatenates those chunks internally. Each request contains offset
and length variables that specify which portion of the result shall be
retrieved.
Today, Winedbg handles this by generating the entire result data each
time a request is received and slicing out the requested range for the
response. This is not only inefficient due to repeated computation,
but also prone to race condition since the result may change between
successive chunk requests due to the dynamic nature of some commands
such as "libraries" and "threads."
Fix this by cacheing the result into a buffer at the first request, and
use the buffer to serve successive chunk requests. The cache is
invalidated when the remote requests a different object, or the debugger
reaches the end of the result cache buffer.

Define a handler lookup table for qXfer commands and use it.
This facilitates implementing more qXfer commands and cacheing reply
data.

Some dynamic strings (e.g. loaded image paths) may contain XML special
characters which breaks parsing.
Fix this by escaping all dynamic strings (i.e. character data and
attribute values) that go into the XML replies.
