mingw32: Open file using _wsopen and added --enable-mmap support
I tried CreateFile but the subsequent ReadFile fails with Access
Denied if sparse file is read on NTFS. I mostly reverted previous
changes and use _wsopen with read/write share enabled instead of
CreateFile.
This change also includes --enable-mmap support for MinGW32
build. Memory mapped file may be useful for 64-bits OS and lots of
RAM. Currently, FlushViewOfFile is not called during the download, so
it is slightly vulnerable against sudden power loss. I found lots of
read when resuming download due to page fault. So for now it is useful
for the initial download. I recommend not to use
--file-allocation=prealloc with --enable-mmap for MinGW32, because it
triggers page faults even in the initial download. Anyway, the option
is experimental.
