Aside from being faster, it also requires less code.
This commit also changes the way architecture is detected for Win32 processes.
Previously, we relied on the Wine's preloader binary's architecture because we read its ELF header; now we read the NT header(s) by calling isWin32Process64Bit() (implemented in 86154c8234).
This is in preparation for the new Source Engine plugin which will add a few common functions.
This commit also improves the functions arguments so that they are passed by reference and marked as const (when possible).
A new data type called procid_t is created, intended to be a replacement for pid_t (Linux) and DWORD (Windows).
This commit removes the architecture-specific headers, by keeping only the OS-specific ones.
The different headers were needed to keep the legacy Windows header, after we created the "procptr32_t" (4 bytes) and "procptr64_t" (8 bytes) variables.
We created these variables because the "peekProc" functions read as many bytes as the variable can hold. A pointer is 4 bytes on 32 bit platforms and 8 bytes on 64 bit ones.
Now there's a new variable, called "procptr_t" and with a size of 8 bytes (unsigned long long).
We had a "peekProc" template function which returned the value stored at the specified memory address, but it has been used only to read pointers so far.
Since we needed a new function that checks the process architecture and sets the correct size of the memory to read, I decided to "recycle" it.
