Fix various bugprone warnings (#397)

Browse Source 
* Fix some warnings in main.c

main.c:678: narrowing conversion from 'unsigned long' to signed type 'int' is implementation-defined
main.c:493: The return value from the call to 'seteuid' is not checked.

* Fix some warnings in array operations

Instead of extracting typenumbers to an 'int', use the unsigned typenumber directly

array3.c:49: narrowing conversion from 'unsigned int' to signed type 'int' is implementation-defined
array4.c:61: narrowing conversion from 'unsigned int' to signed type 'int' is implementation-defined
array5.c:63: narrowing conversion from 'unsigned int' to signed type 'int' is implementation-defined
array6.c:50: narrowing conversion from 'unsigned int' to signed type 'int' is implementation-defined

* Resolve type mismatches for version numbers and propp flag

dir.c:1849: narrowing conversion from 'unsigned int' to signed type 'int'
dir.c:1850: narrowing conversion from 'unsigned int' to signed type 'int'
dir.c:2114: narrowing conversion from 'unsigned long' to signed type 'int'
dir.c:2207: narrowing conversion from 'unsigned int' to signed type 'int'

* Resolve type mismatches for version numbers and strlen result type

dsk.c:1072: narrowing conversion from 'unsigned long' to signed type 'int'
dsk.c:1108: narrowing conversion from 'unsigned long' to signed type 'int'
dsk.c:1549: narrowing conversion from 'unsigned long' to signed type 'int'
dsk.c:1712: narrowing conversion from 'unsigned long' to signed type 'int'
dsk.c:1751: narrowing conversion from 'unsigned long' to signed type 'int'
dsk.c:3426: narrowing conversion from 'unsigned int' to signed type 'int'

* Resolve type mismatches for strlen result type

ufs.c:213: narrowing conversion from 'unsigned long' to signed type 'int'
ufs.c:404: narrowing conversion from 'unsigned long' to signed type 'int'

* Resolve type error
