RelocAlloc: Using .reloc section to replace the typical allocation calls

Explaining the code:

• We first, locate the addresses of all the dlls mapped to our process.
• We then construct an array of structs and we fill it up with some data, thats Initialize() function.
• Now, we have a full array, next step is to search for the right address.
• calling GetSuitableAddress(SIZE_T ShellcodeSize) will do the job; thats finding us the right code cave (empty place in memory, fitting the shellcode size)
• in case it is found it will be returned.
• to use it we must adjust memory protection to be writable/executable ... (the poc is directly rwx)

Demo:

Note: this only work with small shellcodes, bcz it depends on the dlls mapped, the bigger the .reloc section, the bigger chances of getting a valid address. In addition, this is tested only on a x64 machine, but it should work for x86 (i think :p)
