Add syscall-x86-{32,64} for dcs #1025
Fix the w64 profile
Use more SDB into rsyscall module
Fix 'dcc'
Fix for crash when using regexp searches

Since commit baf31455989ce1b3b2268e0d80e6b90b002afa9a buffers for
bin_keyword and bin_keymask at RSearchKeyword structure need to be
allocated dynamilly. The allocation was missing causing a crash.

Added check to avoid empty regexp filters
Added JSON output support for multiple search cmds

JSON output support has been added for the following cmds:
| / foo\x00              search for string 'foo\0'                         // Si
| /j foo\x00             search for string 'foo\0' (JSON output)           // Si
| /! ff                  search for first occurrence not matching          // Si
| /+ /bin/sh             construct the string with chunks                  // No
| /!x 00                 inverse hexa search (find first byte != 0x00)     // No
| //                     repeat last search                                // Si
| /a jmp eax             assemble opcode and search its bytes              // Si

| /R [grepopcode]        search for matching ROP gadgets, comma-separated  // Si
| /v[1248] value         look for an `asm.bigendian` 32bit value           // Si

| /wi foo                search for wide string ignoring case 'f\0o\0o\0'  // Si
